[ 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.
Fixes: 1c5bd76d17cca ("pNFS: Enable layoutreturn operation for...")
