KVM: selftests: x86: clarify what is reported on KVM_GET_MSRS failure
When KVM_GET_MSRS fail the report looks like ==== Test Assertion Failure ==== lib/x86_64/processor.c:1089: r == nmsrs pid=28775 tid=28775 - Argument list too long 1 0x000000000040a55f: vcpu_save_state at processor.c:1088 (discriminator 3) 2 0x00000000004010e3: main at state_test.c:171 (discriminator 4) 3 0x00007fb8e69223d4: ?? ??:0 4 0x0000000000401287: _start at ??:? Unexpected result from KVM_GET_MSRS, r: 36 (failed at 194) and it's not obvious that '194' here is the failed MSR index and that it's printed in hex. Change that.
