Set the SW prio_tc values at initialization to the HW setting.
Setting the SW prio_tc default values to be the HW setting by reading the
rtrup2tc register. For any TC change we need to reset the device.
This will remove the need to reset the device at the first
time we call ixgbe_dcbnl_ieee_setets.

This change makes it so the function ixgbe_dcb_get_tc_from_up will use the
num_tcs.pg_tcs to determine the starting value for determining a traffic
class based on a user priority. The main motivation for this change is to
address possible bad configurations in which more TCs worth of data are
populated then there are actual TCs. By limiting this value we can at
least make certain we are not providing a map with values that are out of
range.
As a result any user priorities that are setup in the configuration with a
traffic class mapping higher than what the hardware supports will be
reported as being on TC 0.

There were cases where the prio_tc_map was not populated when we were
calling open. This will result in us incorrectly configuring the traffic
classes when DCB is enabled. In order to correct this I have updated the
code so that we now populate the values prior to allocating the q_vectors
and calling ixgbe_open.

This is meant to be a generic clean-up of the remaining functions for
unpacking data from the DCB structures. The only real changes are:
replaced the variable i with tc for functions that were looping through the
traffic classes, and added a pointer for tc_class instead of path since
that way we only need to pull the pointer once instead of once per loop.

This patch is meant to help simplify the logic for getting traffic classes
from user priorities. To do this I am adding a function named
ixgbe_dcb_get_tc_from_up that will go through the traffic classes in
reverse order in order to determine which traffic class contains a bit for
a given user priority.
Adding a declaration for this new function to the header so that
we have a centralized means for sorting out traffic classes belonging to
features such as FCoE.

The DCB CEE command set_state() will complete successfully
but is misleading because it enables IEEE mode. After
this patch the command is failed.
And IEEE PFC/ETS is managed from ieee paths now instead
of using CEE primitives.
