qcom-charger: Fix voting issues on parallel charging

Browse source 
The current driver simply skips checking for other events in the
typec change interrupt if an vbus error is seen. This could cause
parallel charging to never get enabled among other issues.

Fix is by simply printing a debug messages for vbus-error and
handling other events.
