NFS: Fix nfs_migrate_page()
commit 190f38e5cedc910940b1da9015f00458c18f97b4 upstream.
The call to migrate_page() will cause the page->private field to be
cleared.
Also fix up the locking around the page->private transfer, so that we ensure
that calls to nfs_page_find_request() don't end up racing.
Finally, fix up a double free bug: nfs_unlock_request() already calls
nfs_release_request() for us...
