adds LO_FLAGS_AUTOCLEAR for loop device of zram backing device
Userdata spaces leak when zram writeback is enable and repeatedly kill
system_server(restart android).
The reason is that per_boot‘s inode is hold by loop device
although per_boot is deleted by user which become orphan inode in system.
Adds LO_FLAGS_AUTOCLEAR for loop device of zram backing device,
so loop device can release resouce.
