Thadeu Lima de Souza Cascardo 3784576fc6 alarmtimer: Use EOPNOTSUPP instead of ENOTSUPP 
commit f18ddc13af upstream.

ENOTSUPP is not supposed to be returned to userspace. This was found on an
OpenPower machine, where the RTC does not support set_alarm.

On that system, a clock_nanosleep(CLOCK_REALTIME_ALARM, ...) results in
"524 Unknown error 524"

Replace it with EOPNOTSUPP which results in the expected "95 Operation not
supported" error.

Fixes: 1c6b39ad3f (alarmtimers: Return -ENOTSUPP if no RTC device is present)
