[SCSI] bfa: io tag handling and minor bug fix.
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.
