platform/x86/amd/pmf: Fix possible out-of-bound memory accesses
The length of the policy buffer is not validated before accessing it,
which means that multiple out-of-bounds memory accesses can occur.
This is especially bad since userspace can load policy binaries over
debugfs.
Compile-tested only.
