wifi: iwlwifi: mvm: don't always unblock EMLSR

Browse Source 
When an event occurs to unblock EMLSR, the code attempts to re-enable
EMLSR. However, the current implementation always tries to activate
EMLSR, regardless of whether the blocker was set before the unblocking
event or not. If EMLSR was already unblocked, there is no need to
re-activate it.

Fixes: 6cf7df9f01 ("wifi: iwlwifi: mvm: Add helper functions to update EMLSR status")
