LU-13470 ptlrpc: return proper write count from ping_store
If we return 0 as a measure of success, that is actually taken
by userspace as "we wrote 0 bytes, but there's no error, so
they want us to retry". So tell them we ate all their data
instead to make them happy.
Interesting that when you do shell-redirect it enters the
retry loop, but badarea_io does not.
