We cannot wait on a completion object in the lpfc_nvme_lport structure in
the _destroy_localport() code path because the NVMe/fc transport will free
that structure immediately after the .localport_delete() callback. This
results in a use-after-free, and a hang if slub_debug=FZPU is enabled.
Fix this by putting the completion on the stack.
