nvmet: Finish the blk plug when integrity allocation fails

nvmet_bdev_execute_rw() starts a plug before building the bios, but
the two error exits taken when nvmet_bdev_alloc_bip() fails return
without calling blk_finish_plug().  current->plug is left pointing
at the stack frame of the returned function, so the next
blk_flush_plug() walks a stale list.

Route both failures through a common exit that finishes the plug.
