KDB can interrupt any console to execute the "mirrored printing" at any time, so add an exception to nbcon_context_try_acquire_direct to allow to get the context if the current CPU is the same as kdb_printf_cpu. This change will be necessary for the next patch, which fixes kdb_msg_write to work with NBCON consoles by calling ->write_atomic on such consoles. But to print it first needs to acquire the ownership of the console, so nbcon_context_try_acquire_direct is fixed here.
