Subject: [PATCH 4.4 002/117] NFSv4.1/pnfs: Fixup an lo->plh_block_lgets imbalance in layoutreturn

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Trond Myklebust <trond.myklebust@...marydata.com>

commit 1a093ceb053832c25b92f3cf26b957543c7baf9b upstream.

Since commit 2d8ae84fbc32, nothing is bumping lo->plh_block_lgets in the
layoutreturn path, so it should not be touched in nfs4_layoutreturn_release
either.

Fixes: 2d8ae84fbc32 ("NFSv4.1/pnfs: Remove redundant lo->plh_block_lgets...")
