Fix iotag handling:
1) Update and check io tag for retry case.
2) Clearing upper 3 bits in io tag when an IO completes.
The 3 upper bits in io tags are used for counting FCP exchange retry.
Un-cleared bits will cause firmware to access invalid memory when the
same io tag is used for an IO to a target that doesn't support FCP
exchange retry.
3) Only check the effective bits when validating an iotag.
Other minor fixes:
1) Added trace to get FC header type with assert of unhandled packet received.
Ignore the type FC_TYPE_FC_FSS (FC_XS).
2) Fixed the adapter info display check - to check for fcmode flag even.

Modified scatter gather processing to use the kernel provided
scsi_for_each_sg() macro.
1) Instead of allocating and setting up sgpg in bfa_ioim_sge_setup(),
we only do allocation. As a result, we remove
bfa_ioim_sgpg_setup() and rename bfa_ioim_sge_setup() to
bfa_ioim_sgpg_alloc().
2) bfa_ioim_send_ioreq() call scsi_for_each_sg() to handle both inline
and sgpg setup.

This patch addresses the comments from Randy Dunlap (Randy.Dunlap@oracle.com)
regarding comment blocks that begining with "/**". bfa driver comments
currently do not follow kernel-doc convention, we hence replace all
/** with /* and **/ with */.

This patch removes os wrapper and unused functions.
bfa_os_assign(), bfa_os_memset(), bfa_os_memcpy(), bfa_os_udelay()
bfa_os_vsprintf(), bfa_os_snprintf(), and bfa_os_get_clock() are replaced with
direct assignment or native linux functions. Some unused functions related to VF
(Vitual fabric) are also removed.
