drm amdgpu: Skip tmr load for SRIOV

Browse Source 
1. For Navi12, CHIP_SIENNA_CICHLID, skip tmr load operation;
2. Check pointer before release firmware.

v2: use CHIP_SIENNA_CICHLID instead
v3: remove local "bool ret"; fix grammer issue
v4: use my name instead of "root"
v5: fix grammer issue and indent issue
