msm: limits: lmh_lite: Avoid deadlock while clearing work event

There is a possibility for deadlock situation when the
sensor reset API has acquired the write lock and tries to
clear the work event, which is already waiting on the
same lock.

In the reset API, update the polling status within the
critical section and try to clear the work event outside
of the critical section to avoid this deadlock.
