usb: pd: Fix sink hard reset looping bug
commit f2449fb61a25 ("usb: pd: Clear PD_IN_HARD_RESET in
PE_SNK_TRANSITION_TO_DEFAULT") introduced a subtle bug by
moving the clearing of the pd->hard_reset flag in sink mode
to the PE_SNK_TRANSITION_TO_DEFAULT state. This caused a
regression in which the state machine acts as if it had
received a hard reset signal and infinitely loops back there.
The cycle could only be broken if a physical disconnect happens.
Fix this by renaming the flag to hard_reset_recvd and only using
it when receiving, and not sending a hard reset.
