Omar Sandoval cd3db55c64 loop: fix LO_FLAGS_PARTSCAN hang ...

commit e02898b423 upstream.

loop_reread_partitions() needs to do I/O, but we just froze the queue,
so we end up waiting forever. This can easily be reproduced with losetup
-P. Fix it by moving the reread to after we unfreeze the queue.

Fixes: ecdd09597a ("block/loop: fix race between I/O and set_status")
