drm/etnaviv: fix reference leak when mmaping imported buffer
drm_gem_prime_mmap() takes a reference on the GEM object, but before that
drm_gem_mmap_obj() already takes a reference, which will be leaked as only
one reference is dropped when the mapping is closed. Drop the extra
reference when dma_buf_mmap() succeeds.
