drivers: macintosh: rack-meter: really fix bogus memsets 

[ Upstream commit e283655b5a ]

We should zero an array using sizeof instead of number of elements.

Fixes the following compiler (GCC 7.3.0) warnings:

drivers/macintosh/rack-meter.c: In function 'rackmeter_do_pause':
drivers/macintosh/rack-meter.c:157:2: warning: 'memset' used with length equal to number of elements without multiplication by element size [-Wmemset-elt-size]
drivers/macintosh/rack-meter.c:158:2: warning: 'memset' used with length equal to number of elements without multiplication by element size [-Wmemset-elt-size]
