pw_transfer: Support filling a receive buffer

Previously, transfers would fail if the client set pending_bytes to 0,
even if there were no more bytes to send. This made it impossible for
the C++ client to completely fill its receive buffer.

This change permits the receiver to set pending_bytes to 0. The transfer
aborts with an error if there is still data to send, but completes
successfully if there is no more data.
