s390/startup: correct "dfltcc" option parsing

Browse source

Currently if just "dfltcc" is passed as a kernel command line option
"val" going to be NULL, this leads to reading at address 0 in
strcmp(val, "off")

Fix that by making sure "val" is not NULL. This does not affect option
handling logic.
