Improper validation of command line arguments received from u-boot

In start_netbsd, it should be ensured that cmdline(the command line arguments received from u-boot) is not an empty string but current check only ensures that cmdline is not NULL. Fixing this moves the boot process ahead - now it fails when searching for boot partitions.
