In the SRC_READY state, we'll only request sink caps if we haven't received them yet and only if its the first transition to the state. However, we also don't send any PD traffic in that state if there's an incoming message in order to prevent a collision. This could create a scenario where upon entry to the SRC_READY state, a message is incoming. When this occurs, we never request the sink caps. This commit simply removes the condition that we may only request sink caps on the first transition to the SRC_READY state. BUG=b:64037926 BRANCH=gru TEST=Flash kevin; Connect to a DR port partner; Verify that sink caps are requested even after the first transition to the SRC_READY state.
