bootconfig: Fix to prevent warning message if no bootconfig option
Commit de462e5f1071 ("bootconfig: Fix to remove bootconfig data from initrd while boot") causes a cosmetic regression on dmesg, which warns "no bootconfig data" message without bootconfig cmdline option. Fix setup_boot_config() by moving no bootconfig check after commandline option check.
