scsi: qla2xxx: Remove two superfluous if-tests
This patch fixes the following Coverity complaint:
Null-checking sp->u.iocb_cmd.u.ctarg.rsp suggests that it may be null, but
it has already been dereferenced on all paths leading to the check.
See also commit e374f9f59281 ("scsi: qla2xxx: Migrate switch registration commands away from mailbox interface") # v4.16.
