ext4: initialize quota before expanding inode in setproject ioctl
commit 1485f726c6dec1a1f85438f2962feaa3d585526f upstream.
Make sure we initialize quotas before possibly expanding inode space
(and thus maybe needing to allocate external xattr block) in
ext4_ioctl_setproject(). This prevents not accounting the necessary
block allocation.
