commit cc77e2ce187d26cc66af3577bf896d7410eb25ab upstream.
Disabling link power management on Samsung SSD 870 QVO drives to make them work again after the switch of the default LPM policy to low.
Testing so far has shown that regular Samsung SSD 870 (the non QVO variants) do not need it and work fine with the default LPM policy.
