metag: Only define atomic_dec_if_positive conditionally
commit 35d04077ad96ed33ceea2501f5a4f1eacda77218 upstream.
The definition of atomic_dec_if_positive() assumes that
atomic_sub_if_positive() exists, which is only the case if
metag specific atomics are used. This results in the following
build error when trying to build metag1_defconfig.
kernel/ucount.c: In function 'dec_ucount':
kernel/ucount.c:211: error:
implicit declaration of function 'atomic_sub_if_positive'
Moving the definition of atomic_dec_if_positive() into the metag
conditional code fixes the problem.
Fixes: 6006c0d8ce94 ("metag: Atomics, locks and bitops")
