scsi: lpfc: Check for hdwq null ptr when cleaning up lpfc_vport structure



[ Upstream commit 6698796282e828733cde3329c887b4ae9e5545e9 ]

If a call to lpfc_sli4_read_rev() from lpfc_sli4_hba_setup() fails, the
resultant cleanup routine lpfc_sli4_vport_delete_fcp_xri_aborted() may
occur before sli4_hba.hdwqs are allocated.  This may result in a null
pointer dereference when attempting to take the abts_io_buf_list_lock for
the first hardware queue.  Fix by adding a null ptr check on
phba->sli4_hba.hdwq and early return because this situation means there
must have been an error during port initialization.
