block: return errors from bdrv_register_buf()

Browse source 
Registering an I/O buffer is only a performance optimization hint but it
is still necessary to return errors when it fails.

Later patches will need to detect errors when registering buffers but an
immediate advantage is that error_report() calls are no longer needed in
block driver .bdrv_register_buf() functions.
