Allow a longer timeout for i2c due to clock stretching and
inaccurate jiffy timing when under a spin lock. This timeout
is consistent with other i2c-algo-bit users.

The monitor values from bytes 22 through 81 of the QSFP memory space
(SFF 8636) are dynamic and serving them out of the QSFP memory cache
maintained by the driver provides stale data to the CableInfo SMA query.
This patch refreshes the dynamic values from the QSFP memory on request
and overwrites the stale data from the cache for the overlap between the
requested range and the monitor range.

This fixes potential buffer overflow because the sprintf function
doesn't check buffer boundaries. Use snprintf instead.

The TODO list for the hfi1 driver was completed during 4.6. In addition
other objections raised (which are far beyond what was in the TODO list)
have been addressed as well. It is now time to remove the driver from
staging and into the drivers/infiniband sub-tree.
