Bjoern Walk <bwalk@xxxxxxxxxxxxxxxxxx> [2016-07-08, 12:34PM +0200]:
Since return code is checked globally at the end of the function, let's
make sure that we set it correctly at any point.

This fixes a regression introduced in commit 0aa19f35 where the first
command to eject changeable media would fail unconditionally.
