NFS: Don't recoalesce on error in nfs_pageio_complete_mirror()
commit 8127d82705998568b52ac724e28e00941538083d upstream.
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")
