Vitaly Kuznetsov 13ffbd8db1 KVM: selftests: fix rdtsc() for vmx_tsc_adjust_test
vmx_tsc_adjust_test fails with:

IA32_TSC_ADJUST is -4294969448 (-1 * TSC_ADJUST_VALUE + -2152).
IA32_TSC_ADJUST is -4294969448 (-1 * TSC_ADJUST_VALUE + -2152).
IA32_TSC_ADJUST is 281470681738540 (65534 * TSC_ADJUST_VALUE + 4294962476).
==== Test Assertion Failure ====
  x86_64/vmx_tsc_adjust_test.c:153: false
  pid=19738 tid=19738 - Interrupted system call

     3	0x0000000000401201: _start at ??:?
  Failed guest assert: (adjust <= max)

The problem is that is 'tsc_val' should be u64, not u32 or the reading
gets truncated.
