rtc: fix double lock on UIE emulation
With commit 5ad31a575157147b43fa84ef1e21471661653878 ("rtc: remove BKL
for ioctl()"), RTC_UIE_ON ioctl cause double lock on rtc->ops_lock.
The ops_lock must not be held while set_uie() calls rtc_read_time()
which takes the lock. Also clear_uie() does not need ops_lock. This
patch fixes return value of RTC_UIE_OFF ioctl too.
