qcom-charger: qpnp-smb2: update usb type on PD_ACTIVE

There is a race condition between setting PD_ACTIVE = 0 and when losing CC.
If PD_ACTIVE is not set to 0 by the time the TYPE_C interrupt fires on
disconnect then the POWER_SUPPLY_TYPE will not be set to UNKNOWN.

Instead of relying on PD_ACTIVE being set to 0 before the TYPE_C interrupt
fires, just update the type upon PD_ACTIVE being set.
