drm/amd/pm: vega10_hwmgr: fix potential off-by-one overflow in 'performance_levels' 

Since 'hardwareActivityPerformanceLevels' is set to the size of the
'performance_levels' array in vega10_hwmgr_backend_init(), using the
'<=' assertion to check for the next index value is incorrect.
Replace it with '<'.

Detected using the static analysis tool - Svace.
