Paolo Bonzini 2f8ebe43a0 KVM selftests fixes/cleanups (and one KVM x86 cleanup) for 6.8:
- Remove redundant newlines from error messages.
 
  - Delete an unused variable in the AMX test (which causes build failures when
    compiling with -Werror).
 
  - Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails with an
    error code other than ENOENT (a Hyper-V selftest bug resulted in an EMFILE,
    and the test eventually got skipped).
 
  - Fix TSC related bugs in several Hyper-V selftests.
 
  - Fix a bug in the dirty ring logging test where a sem_post() could be left
    pending across multiple runs, resulting in incorrect synchronization between
    the main thread and the vCPU worker thread.
 
  - Relax the dirty log split test's assertions on 4KiB mappings to fix false
    positives due to the number of mappings for memslot 0 (used for code and
    data that is NOT being dirty logged) changing, e.g. due to NUMA balancing.
 
  - Have KVM's gtod_is_based_on_tsc() return "bool" instead of an "int" (the
    function generates boolean values, and all callers treat the return value as
    a bool).
