btrfs-progs: check: drop exclusive open mode for --force
The check opens the given device in exclusive by default. In the forced
mode we want to access a device in use, so we have to drop the
exclusivity bit.
This works for block devices but not for files, that could be mounted
via a loop device. In that respect test check/007 is broken and will be
fixed.
