[PATCH 2/4] KVM: selftests: Delete dead ucall code from emulator_error_test

[David Matlack <dmatlack@xxxxxxxxxx>]

Delete a bunch of code related to ucall handling from
emulator_error_test. The only thing emulator_error_test needs to check
is that the vCPU exits with UCALL_DONE after the second vcpu_run().

No functional change intended.
