Sean Anderson 7aaddea446 iio: xilinx-ams: Unmask interrupts after updating alarms 
commit feb500c7ae upstream.

To convert level-triggered alarms into edge-triggered IIO events, alarms
are masked when they are triggered. To ensure we catch subsequent
alarms, we then periodically poll to see if the alarm is still active.
If it isn't, we unmask it. Active but masked alarms are stored in
current_masked_alarm.

If an active alarm is disabled, it will remain set in
current_masked_alarm until ams_unmask_worker clears it. If the alarm is
re-enabled before ams_unmask_worker runs, then it will never be cleared
from current_masked_alarm. This will prevent the alarm event from being
pushed even if the alarm is still active.

Fix this by recalculating current_masked_alarm immediately when enabling
or disabling alarms.
