scsi: lpfc: Fix crash in lpfc_sli_ringtxcmpl_put when nvmet gets an abort request.
When running nvme detach-ns /dev/nvme0n1 -n 1 command, the nvmet lpfc
driver crashes with this stack dump:
kernel BUG at /root/NVME/lpfc_8.4/lpfc_sli.c:1393!

Crash is due to an uninitialized iocbq->vport pointer.
Explicitly set the iocbq->vport field to phba->pport in
lpfc_nvmet_sol_fcp_issue_abort as it does all abort iocbq initialization
in the routine. Using phba->pport is ok because target does not support
NPIV instances.
