compositor-drm: Refactor destroy drm_fb function

Browse Source 
The drm_fb destroy callback to mostly the same thing regardless of
whether the buffer is a dumb buffer or gbm buffer. This patch refactors
the common parts into a new function that can be called for both cases.

[daniels: Rebased on top of fb->fd changes, cosmetic changes.]
