I've significantly changed firmware loading in wireless-testing which
should hit the next merge window.  It won't have this problem, and it
does correctly release the firmware later on.  It does preserve the
existing behavior of releasing the firmware after load, instead of
keeping it around for resume.  If there are fixes I think they should be
against wireless-testing actually since that's what's "next".
