scsi: lpfc: Fix crash when lpfc_sli4_hba_setup() fails to initialize the SGLs 

[ Upstream commit 5aa615d195f1e142c662cb2253f057c9baec7531 ]

The driver is encountering a crash in lpfc_free_iocb_list() while
performing initial attachment.

Code review found this to be an errant failure path that was taken, jumping
to a tag that then referenced structures that were uninitialized.

Fix the failure path.
