memleak: gsmtap_sendmsg(): don't return 0 when no data was written
If less than the msgb size was written by write(), we want to return -EIO.
Hence do not return zero when write() wrote zero bytes, return -EIO in that
case as well.
Previously, if write() returned zero, gsmtap_sendmsg() would return zero
*without* freeing the msg, hence neither would the (ideal) caller. So this
fixes a corner-case memleak.
