[PATCH RFC 014/111] staging: etnaviv: fix cleanup of imported dmabufs

[Lucas Stach]

From: Russell King <rmk+ker...@arm.linux.org.uk>

We need to call drm_prime_gem_destroy() to properly clean up imported
dmabufs when their associated GEM object is deleted, otherwise we drop
a refcount on them, preventing them from being cleaned up.
