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. Signed-off-by: Ewan D.
