[media] atomisp: Fix -Werror=int-in-bool-context compile errors
With gcc-7.1.1 I was getting the following compile error:
error: ‘*’ in boolean context, suggest ‘&&’ instead
The problem is the definition of CEIL_DIV:
#define CEIL_DIV(a, b) ((b) ? ((a) + (b) - 1) / (b) : 0)
Which when called as: CEIL_DIV(x, y * z) triggers this error, note
we cannot do as the error suggests since b is evaluated multiple times.
This commit fixes these compile errors.
