msm: timer: Don't check state of clock while setting next timer event

The commit fd6681cd4d0782f6e6ac918ab337016f59c2520b introduced
a silent bug that incorrectly checks state of the clock while
setting the next timer event. The bug manifests only during
failure code path of msm idle operation, which is very rare.
Due to the bug, the driver isn't be able to reprogram the timer
device.
