mhi: host: Notify MHI clients about fatal error

Browse Source 
Currently fatal error notification is done from
fast resume path. This does not cover RDDM EE
change via BHI Intvec. As a result of the some
critical clients are unable to perform cleanup
and does not come up after recovery. In case
if RDDM EE change never comes notify clients
from mhi force reset context.
