    [SCSI] bfa: io tag handling and minor bug fix. · 15821f05

    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.
