nfs: Fix "Don't increment lock sequence ID after NFS4ERR_MOVED"


[ Upstream commit 406dab84 ]

Lock sequence IDs are bumped in decode_lock by calling
nfs_increment_seqid(). nfs_increment_sequid() does not use the
seqid_mutating_err() function fixed in commit 059aa734 ("Don't
increment lock sequence ID after NFS4ERR_MOVED").

Fixes: 059aa734 ("Don't increment lock sequence ID after ...")
