[PATCH] Trivial apm update: eliminate 0 initializers

Second in a series of patches from Thomas Hood.

This patch eliminates the 0 initializers on three
static variables inside the apm_cpu_idle function.
These initializers are superfluous.

The initializers are replaced with comments whose
purpose is to indicate that the code relies upon the
fact that these variables are initialized to zero
at load time.
