thunderbolt: Fix bit masking in tb_dp_port_set_hops()

The tb_dp_port_set_hops() function was incorrectly clearing
ADP_DP_CS_1_AUX_RX_HOPID_MASK twice. According to the function's
purpose, it should clear both TX and RX AUX HopID fields.  Replace the
first instance with ADP_DP_CS_1_AUX_TX_HOPID_MASK to ensure proper
configuration of both AUX directions.
