Patch for libcdio-0.81 FreeBSD drive lock

[John Wehle]

A side effect of opening the cdrom device on FreeBSD is it
locks the drive.  This makes cdio_get_media_changed less
useful and prevents you from being able to switch disks
when using things such as the audacious media player.

This patch simply unlocks the drive right after it's opened
prior to opening the cam passthrough device.
