From: "Tyler Hicks" <code@tyhicks.com>

The backport of commit 05c2224d4b04 ("KVM: selftests: Fix number of
pages for memory slot in memslot_modification_stress_test") broke the
build of the KVM selftest memslot_modification_stress_test.c source file
in two ways:

- Incorrectly assumed that max_t() was defined despite commit
5cf67a6051ea ("tools/include: Add _RET_IP_ and math definitions to
kernel.h") not being present
- Incorrectly assumed that kvm_vm struct members could be directly
accessed despite b530eba14c70 ("KVM: selftests: Get rid of
kvm_util_internal.h") not being present

Backport the first commit, as it is simple enough. Work around the lack
of the second commit by using the accessors to get to the kvm_vm struct
members.

Note that the linux-6.0.y backport of commit 05c2224d4b04 ("KVM:
selftests: Fix number of pages for memory slot in
memslot_modification_stress_test") is fine because the two prerequisite
commits, mentioned above, are both present in v6.0.
