Nicolas Iooss 0d1da3c152 drm/amd/powerplay: initialize a variable before using it
Function vega10_apply_state_adjust_rules() only initializes
stable_pstate_sclk_dpm_percentage when
data->registry_data.stable_pstate_sclk_dpm_percentage is not between 1
and 100. The variable is then used to compute stable_pstate_sclk, which
therefore uses an uninitialized value.

Fix this by initializing stable_pstate_sclk_dpm_percentage to
data->registry_data.stable_pstate_sclk_dpm_percentage.

This issue has been found while building the kernel with clang. The
compiler reported a -Wsometimes-uninitialized warning.
