bus: mhi: core: Fix sys error transition latency

Bring forward the idea to fix the power down latency in
mhi_pm_disable_transition() further to mhi_pm_sys_error_transition()
so that the transition into system error (triggered by AT!RESET) in the
modems won't have to return only after the timeout of up to 24 seconds.

Once the device gets reset, there is no guarantee that it will send an
interrupt to indicate the state transition. So polling is the sensible
option here.
