NFS/pNFS: Fix a leak of the layout 'plh_outstanding' counter

Browse source 
commit cb2856c597 upstream.

If we exit _lgopen_prepare_attached() without setting a layout, we will
currently leak the plh_outstanding counter.

Fixes: 411ae722d1 ("pNFS: Wait for stale layoutget calls to complete in pnfs_update_layout()")
