When running nvme detach-ns /dev/nvme0n1 -n 1 command,
the nvmet lpfc driver crashes with this stack dump:

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.
