I'll queue it up for 3.4.y. Thanks!
(NFS4CLNT_RECLAIM_NOGRACE was suppose to be NFS_STATE_RECLAIM_NOGRACE)

3.4.110-rc1 review patch. If anyone has any objections, please let me know.
------------------
commit e8d975e73e5fa05f983fbf2723120edcf68e0b38 upstream.
Problem: When an operation like WRITE receives a BAD_STATEID, even though
recovery code clears the RECLAIM_NOGRACE recovery flag before recovering
the open state, because of clearing delegation state for the associated
inode, nfs_inode_find_state_and_recover() gets called and it makes the
same state with RECLAIM_NOGRACE flag again. As a results, when we restart
looking over the open states, we end up in the infinite loop instead of
breaking out in the next test of state flags.
Solution: unset the RECLAIM_NOGRACE set because of
calling of nfs_inode_find_state_and_recover() after returning from calling
recover_open() function.
