NFS: Fix missing pg_cleanup after nfs_pageio_cond_complete()
[ Upstream commit 43b7d964ed30dbca5c83c90cb010985b429ec4f9 ]
Commit a7d42ddb3099727f58366fa006f850a219cce6c8 ("nfs: add mirroring
support to pgio layer") moved pg_cleanup out of the path when there was
non-sequental I/O that needed to be flushed. The result is that for
layouts that have more than one layout segment per file, the pg_lseg is not
cleared, so we can end up hitting the WARN_ON_ONCE(req_start >= seg_end) in
pnfs_generic_pg_test since the pg_lseg will be pointing to that
previously-flushed layout segment.
