drm/amd/pp: Fix potential NULL pointer dereference in atomctrl_initialize_mc_reg_table
The function atomctrl_initialize_mc_reg_table() and
atomctrl_initialize_mc_reg_table_v2_2() does not check the return
value of smu_atom_get_data_table(). If smu_atom_get_data_table()
fails to retrieve vram_info, it returns NULL which is later
dereferenced.
Fixes: b3892e2bb519 ("drm/amd/pp: Use atombios api directly in powerplay (v2)")
Fixes: 5f92b48cf62c ("drm/amd/pm: add mc register table initialization")
