usb: typec: tcpm: avoid sink goto SNK_UNATTACHED state if not received source capability message

Since commit (122968f usb: typec: tcpm: avoid resets for missing
source capability messages), state will change from SNK_WAIT_CAPABILITIES
to SNK_WAIT_CAPABILITIES_TIMEOUT. We need to change SNK_WAIT_CAPABILITIES
-> SNK_READY path to SNK_WAIT_CAPABILITIES_TIMEOUT -> SNK_READY
accordingly. Otherwise, the sink port will never change to SNK_READY state
if the source does't have PD capability.

[  503.547183] pending state change SNK_WAIT_CAPABILITIES -> SNK_WAIT_CAPABILITIES_TIMEOUT @ 310 ms [rev3 NONE_AMS]
[  503.857239] state change SNK_WAIT_CAPABILITIES -> SNK_WAIT_CAPABILITIES_TIMEOUT [delayed 310 ms]
[  503.857254] PD TX, header: 0x87
[  503.862440] PD TX complete, status: 2
[  503.862484] state change SNK_WAIT_CAPABILITIES_TIMEOUT -> SNK_UNATTACHED [rev3 NONE_AMS]
