drm/amd/pm: fix smu table id bound check issue in smu_cmn_update_table()

Browse Source 
[ Upstream commit 238d468d3ed18a324bb9d8c99f18c665dbac0511 ]

'table_index' is a variable defined by the smu driver (kmd)
'table_id' is a variable defined by the hw smu (pmfw)

This code should use table_index as a bounds check.
