Trond Myklebust a2746ab3bb filemap: Fix bounds checking in filemap_read() ...

commit ace149e0830c380ddfce7e466fe860ca502fe4ee upstream.

If the caller supplies an iocb->ki_pos value that is close to the
filesystem upper limit, and an iterator with a count that causes us to
overflow that limit, then filemap_read() enters an infinite loop.

This behaviour was discovered when testing xfstests generic/525 with the
"localio" optimisation for loopback NFS mounts.
