qemu_set_log_filename: filename argument may be NULL
NULL is a valid log filename used to indicate we want to use stderr but qemu_set_log_filename (which is called by bsd-user/main.c) was not handling it correctly. That also made redundant a couple of NULL checks in calling code which have been removed.
