[PATCH v2] rtc: stm32: One condition check and function call less in stm32_rtc_set_alarm()

A condition check was repeated in this function implementation despite of
a corresponding check in the stm32_rtc_alarm_irq_enable() function.
Thus delete redundant source code here.

This issue was detected by using the Coccinelle software.

v2:
Russell King pointed the change possibility out to omit a condition check
at this place.
