btrfs-progs: fix qgroup realloc inheritance 

qgroup.c:82:23: warning: memcpy with byte count of 0
qgroup.c:83:23: warning: memcpy with byte count of 0

The inheritance wasn't copying qgroups[] because a confused sizeof()
gave 0 byte memcpy()s.  It's been like this for the year since it was
merged, so I guess this isn't a very important thing to do :).
