drm/amd/powerplay: Fix maybe-uninitialized in get_ppfeature_status
This fixes the warning below
error: ‘feature_mask’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
*features_enabled = ((((uint64_t)feature_mask[0] << SMU_FEATURES_LOW_SHIFT) & SMU_FEATURES_LOW_MASK) |
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^
(((uint64_t)feature_mask[1] << SMU_FEATURES_HIGH_SHIFT) & SMU_FEATURES_HIGH_MASK));
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
