Fix a -Wlogical-not-parentheses warning

The function returns the number of lowest zero bits of a 32-bit value
and shifts the value by that number. By the time it reaches last
condition x can be zero if and only if the passed value was zero and
hence we can immediately return 32.

Initially the condition were likely supposed to be `if (!(x & 1))` but
in this particular case it's the same as `!x` and subjectively it makes
more sense to just check if the number is zero. See discussion in
the #264.
