skip LAYOUTRETURN if layout is invalid
[ Upstream commit 93b7f7ad2018d2037559b1d0892417864c78b371 ]
Currently, when IO to DS fails, client returns the layout and
retries against the MDS. However, then on umounting (inode eviction)
it returns the layout again.
This is because pnfs_return_layout() was changed in
commit d78471d32bb6 ("pnfs/blocklayout: set PNFS_LAYOUTRETURN_ON_ERROR")
to always set NFS_LAYOUT_RETURN_REQUESTED so even if we returned
the layout, it will be returned again. Instead, let's also check
if we have already marked the layout invalid.
