The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.

virt_machine_device_plug_cb() passes @errp to
cryptodev_builtin_sym_close_session() in a loop.  Harmless, because
cryptodev_builtin_sym_close_session() can't actually fail.  Fix by
dropping its Error ** parameter.
