[SCSI] libfc, fcoe: Remove unnecessary cast by removing inline wrapper

Comment from "Andrew Morton <akpm@linux-foundation.org>"

unneeded/undesirable cast of void*.  There are probably zillions of
instances of this - there always are.

This whole inline function was unnecessary. The FCoE layer knows
that it's data structure is stored in the lport private data, it
can just access it from lport_priv().
