SubjectRe: [PATCH] don't reset alarm interrupt on RTC

We don't unconditionally set it, we just leave it enabled (the code was
uncoditionally UNsetting it). There are ioctl()s to set/unset PIE, AIE,
UIE.

ioctl(fd, RTC_ALM_SET);

if anything, our patch is not correct ENOUGH. none of AIE, PIE, or UIE,
should be molested by rtc_release().
