drm/amd/display: System crashes when add_ptb_to_table() gets called
[Why]
Unused VMIDs were not evicted correctly
[How]
1. evict_vmids() logic was fixed;
2. Added boundary check for add_ptb_to_table() and
clear_entry_from_vmid_table() to avoid crash caused by array out of
boundary;
3. For mod_vmid_get_for_ptb(), vimd is changed from unsigned to signed
due to vimd is signed.
