thunderbolt: Don't access path config space on Lane 1 adapters in tb_switch_reset_host()

Browse source

USB4 Lane 1 adapters do not have accessible path config space. Skip the
path config space cleanup in tb_switch_reset_host() for these ports. The
check is for USB4 switches only. Thunderbolt 1-3 Lane 1 adapters stay as
is because we do need to program their path config space.
