Guenter Roeck 3c54629c64 metag: Only define atomic_dec_if_positive conditionally
commit 35d04077ad 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.
