drm/prime: Remove PRIME handles only if supported
Drivers that don't support PRIME will not have initialized the PRIME
specific private component of struct drm_file. If called for such
drivers, the drm_gem_remove_prime_handles() function will crash. Fix
it by checking for PRIME support prior to removing the PRIME handles.
