nfsd: fix panic in posix_unblock_lock called from nfs4_laundromat
commit 64ebe12494fd5d193f014ce38e1fd83cc57883c8 upstream.
From kernel 4.9, my two nfsv4 servers sometimes suffer from
"panic: unable to handle kernel page request"
in posix_unblock_lock() called from nfs4_laundromat().
These panics diseappear if we revert the commit "nfsd: add a LRU list
for blocked locks".
The cause appears to be a typo in nfs4_laundromat(), which is also
present in nfs4_state_shutdown_net().
