cpu-exec: remove unnecessary check of cpu->exit_request
The cpu->exit_request check in cpu_loop_exec_tb is unnecessary, because cpu->tcg_exit_req is always set after cpu->exit_request. So let the TB exit and we will pick up the exit request later in cpu_handle_interrupt. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
