usb: pd: Ensure disconnect is processed when hard reset in progress



When hard reset is in progress, the pd state machine restarts
from PE_UNKNOWN state. If a Type-C disconnect notification
is received during the same time, the current_pr is set to
PR_NONE. Because of this we bail out of the usbpd_sm
assuming it is in disconnected state even though the
disconnect was not processed.
Fix this by validating the current_dr as well to confirm
that the state machine is actually in disconnected state.
