drm: Hide hw.lock cleanup in filp->release better
A few things:
- Rename the cleanup function from drm_master_release to
drm_legacy_lock_release. It doesn't relase any master stuff, but
just the legacy hw lock.
- Hide it in drm_lock.c, which allows us to make a few more functions
static in there. To avoid forward decl we need to shuffle the code a
bit though.
- Push the check for ->master into the function itself.
- Only call this for !DRIVER_MODESET.
End result: Another place that takes struct_mutex gone for good for
modern drivers.
v2: Remove leftover comment.
