drivers/gpu/drm/amd/amdkfd: use in_compat_syscall to check open() caller type
amdkfd wants to know syscall type, not task type. Check directly.
Unfortunately, amdkfd is making nasty assumptions that a process'
bitness is a well-defined constant thing. This isn't the case on x86.
I don't know how much this matters, but this patch has no effect on
generated code on x86, so amdkfd is equally broken with and without this
patch.
