NFS: Don't recoalesce on error in nfs_pageio_complete_mirror()
If the I/O completion failed with a fatal error, then we should just exit nfs_pageio_complete_mirror() rather than try to recoalesce. Fixes: a7d42ddb3099 ("nfs: add mirroring support to pgio layer") Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com> Cc: stable@vger.kernel.org # v4.0+
