drm/amdkfd: validate SRAT subtables before parsing
The KFD SRAT walker reads the first subtable length without checking
that a header is present and trusts subsequent lengths when accessing
CPU and generic affinity records. Invalid firmware lengths can therefore
cause out-of-bounds reads.
Validate the table header, every generic subtable range, and each
supported typed record before reading its fields.
