[SCSI] aacraid: Fix struct element name issue

Received from Mark Salyzyn,

This patch is to resolve a namespace issue that will result from a patch
expected in the future that adds a new interface; rationalized as
correcting a long term issue where hw_fib, instead of hw_fib_va, refers
to the virtual address space and hw_fib_pa refers to the physical
address space. A small fragment of this patch also cleans up an unused
variable that was close to the patch fragments.
