scsi: fnic: Fix use of uninitialized value in debug message

The oxid variable in fdls_process_abts_req() was only being initialized
inside the if (tport) block, but was being used in a debug print statement
after that block. If tport was NULL, oxid would remain uninitialized.  Move
the oxid initialization to happen at declaration using
FNIC_STD_GET_OX_ID(fchdr).
