drm/i915/tc: Fix the ICL PHY ownership check in TC-cold state

The commit renaming icl_tc_phy_is_in_safe_mode() to
icl_tc_phy_take_ownership() didn't flip the function's return value
accordingly, fix this up.

This didn't cause an actual problem besides state check errors, since
the function is only used during HW readout.
