[PATCH v3 01/10] KVM: selftests: Rename emulator_error_test to smaller_maxphyaddr_emulation_test

Rename emulator_error_test to smaller_maxphyaddr_emulation_test and
update the comment at the top of the file to document that this is
explicitly a test to validate that KVM emulates instructions in response
to an EPT violation when emulating a smaller MAXPHYADDR.
