[PARISC] fix uninitialized variable warning in asm/rtc.h
get_rtc_time, in the case that PDC returns that the battery is bad, returns
an unmodified rtc_time arg to the caller, which then uses uninitialized
values. Fix this by memset-ing the arg with zeroes, so it will at least be
cleared if we return failure.
Spotted by John David Anglin.
