Subject: [PATCH] zram: destroy all devices on error recovery path in
 zram_init()

commit 39a9b8ac9333e4268ecff7da6c9d1ab3823ff243 upstream.

On error recovery path of zram_init(), it leaks the zram device object
causing the failure. So change create_device() to free allocated
resources on error path.
