drm/amd/pm: smu7_hwmgr: fix potential off-by-one overflow in 'performance_levels'
Since 'hardwareActivityPerformanceLevels' is set to the size of the
'performance_levels' array in smu7_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.
Fixes: 599a7e9fe1b6 ("drm/amd/powerplay: implement smu7 hwmgr to manager asics with smu ip version 7.")
