BKL: Remove BKL from fat
The lock_kernel in fat_put_super is not needed because it only protects the super block itself and we know that no other thread can reach it because we are about to kfree the object. In the two fill_super functions, this converts the locking to use lock_super like elsewhere in the fat code. This is probably not needed either, but is consistent and puts us on the safe side.
