selftests: kvm: fix mismatched fclose() after popen()
get_warnings_count() does fclose() using File * returned from popen().
Fix it to call pclose() as it should.
tools/testing/selftests/kvm/x86_64/mmio_warning_test
x86_64/mmio_warning_test.c: In function ‘get_warnings_count’:
x86_64/mmio_warning_test.c:87:9: warning: ‘fclose’ called on pointer returned from a mismatched allocation function [-Wmismatched-dealloc]
87 | fclose(f);
| ^~~~~~~~~
x86_64/mmio_warning_test.c:84:13: note: returned from ‘popen’
84 | f = popen("dmesg | grep \"WARNING:\" | wc -l", "r");
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
