Often the allocated size is of interest and is different from the
requested size. Therefore return allocated size for the object (by
__gem_create_ext()) in gem_create_in_memory_regions() and friends.

Often the allocated size is of interest and is different from the
requested size. Therefore return allocated size for the object (by
__gem_create_ext()) in gem_create_in_memory_regions() and friends.

v2: Assign buf->size correctly in __intel_buf_init (Zbigniew)
