commit 611d0a95d46b0977a530b4d538948c69d447b001 upstream.
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.
