6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sean Christopherson <seanjc@xxxxxxxxxx>

[ Upstream commit 46fee9e38995af9ae16a8cc7d05031486d44cf35 ]

Delete the AMX's tests "stage" counter, as the counter is no longer used,
which makes clang unhappy:

  x86_64/amx_test.c:224:6: error: variable 'stage' set but not used
          int stage, ret;
              ^
  1 error generated.

Note, "stage" was never really used, it just happened to be dumped out by
a (failed) assertion on run->exit_reason, i.e. the AMX test has no concept
of stages, the code was likely copy+pasted from a different test.

Fixes: c96f57b08012 ("KVM: selftests: Make vCPU exit reason test assertion common")
