[PATCH] loop setup calling bd_set_size too soon

From: Chris Mason <mason@suse.com>

I think Andrew and I managed to mismerge the loop setup race fix. 
loop_set_fd is using get_capacity() to read the size of the disk and
sending that to bd_set_size.

But, it is doing this before calling set_capacity, so the size being used
is wrong.  This should clean things up.
