Subject: [PATCH v2 1/7] KVM: selftests: Fix build due to ucall_uninit() removal

From: Mark Brown <broonie@...nel.org>

Today's -next fails to build on arm64 due to:

In file included from include/kvm_util.h:11,
                 from aarch64/page_fault_test.c:15:
include/ucall_common.h:36:47: note: expected ‘vm_paddr_t’ {aka ‘long unsigned int’} but argument is of type ‘void *’
   36 | void ucall_init(struct kvm_vm *vm, vm_paddr_t mmio_gpa);
      |                                    ~~~~~~~~~~~^~~~~~~~
aarch64/page_fault_test.c:725:2: warning: implicit declaration of function ‘ucall_uninit’; did you mean ‘ucall_init’? [-Wimplicit-function-declaration]
  725 |  ucall_uninit(vm);
      |  ^~~~~~~~~~~~
      |  ucall_init

which is caused by commit

interacting poorly with commit

   28a65567acb5 ("KVM: selftests: Drop now-unnecessary ucall_uninit()")

As is done for other ucall_uninit() users remove the call in the newly added
page_fault_test.c.

Fixes: 28a65567acb5 ("KVM: selftests: Drop now-unnecessary ucall_uninit()")
Fixes: 35c581015712 ("KVM: selftests: aarch64: Add aarch64/page_fault_test")
