KVM: selftests: Make TEST_ASSERT_EQ() output look like normal TEST_ASSERT()
Clean up TEST_ASSERT_EQ() so that the (mostly) raw code is captured in the
main assert message, not the helper macro's code. E.g. make this:
x86_64/tsc_msrs_test.c:106: __a == __b
pid=40470 tid=40470 errno=0 - Success
1 0x000000000040170e: main at tsc_msrs_test.c:106
2 0x0000000000416f23: __libc_start_call_main at libc-start.o:?
3 0x000000000041856f: __libc_start_main_impl at ??:?
4 0x0000000000401ef0: _start at ??:?
TEST_ASSERT_EQ(rounded_host_rdmsr(MSR_IA32_TSC), val + 1) failed.
rounded_host_rdmsr(MSR_IA32_TSC) is 0
val + 1 is 0x1
look like this:
x86_64/tsc_msrs_test.c:106: rounded_host_rdmsr(MSR_IA32_TSC) == val + 1
pid=5737 tid=5737 errno=0 - Success
1 0x0000000000401714: main at tsc_msrs_test.c:106
2 0x0000000000415c23: __libc_start_call_main at libc-start.o:?
3 0x000000000041726f: __libc_start_main_impl at ??:?
4 0x0000000000401e60: _start at ??:?
0 != 0x1 (rounded_host_rdmsr(MSR_IA32_TSC) != val + 1)
Opportunstically clean up the formatting of the entire macro.
