pNFS: Ensure we do clear the return-on-close layout stateid on fatal errors

Browse Source 
[ Upstream commit 9c47b18cf722184f32148784189fca945a7d0561 ]

IF the server rejected our layout return with a state error such as
NFS4ERR_BAD_STATEID, or even a stale inode error, then we do want
to clear out all the remaining layout segments and mark that stateid
as invalid.
