Vasily Gorbik 5596c4c106 s390/sclp: remove unused sclp_early_printk_forced
This reverts commit 55a5542a54 ("s390/hibernate: fix error handling when
suspend cpu != resume cpu"). It added sclp_early_printk_force() which
is no longer used since commit 394216275c ("s390: remove broken
hibernate / power management support"). No hibernate - no problem.
