usb: pd: Keep PROP_PR_SWAP set during ERROR_RECOVERY

Since ErrorRecovery handling requires a spoof disconnect, the
charger driver needs to avoid immediately reapplying the
terminations. Re-use the PROP_PR_SWAP property which ignores
the disconnect. After the 25ms delay, policy engine will
explicitly reset back to DRP.

Also remove the transition to ErrorRecovery from PE_SNK_DISCOVERY
as it is removed in V1.3 of the PD 2.0 specification.
