ide: avoid warning for timings calculation
gcc-7 warns about the result of a constant multiplication used as a boolean: drivers/ide/ide-timings.c: In function 'ide_timing_quantize': drivers/ide/ide-timings.c:112:24: error: '*' in boolean context, suggest '&&' instead [-Werror=int-in-bool-context] q->setup = EZ(t->setup * 1000, T); This slightly rearranges the macro to simplify the code and avoid the warning at the same time.
