[PATCH v2 5/6] staging: vchiq_core: Lower indentation in parse_open()

[Umang Jain]

If the service is not in VCHIQ_SRVSTATE_LISTENING state, it is
implied that the message is dealt with and parse_open() should return.
If this is the case, simply jump the code flow to return site using
'goto done;' statement.

This helps to lower the indentation of
	if (service->srvstate == VCHIQ_SRVSTATE_LISTENING)
conditional branch.

No functional changes intended in this patch.
