cnss2: Prevent vote for MHI wake after device error

Ignore MHI wake vote after device error and let MHI driver to
take care the usage count internally.
This change is enabled once again because the dev_vote will
be mismatch if the synchronized wake request is used. After
this change, the cnss_pci_force_wake_release() will also
decrease the dev_vote.
