Alexander Gordeev 5e441f61f5 Revert "s390/smp: rework absolute lowcore access" ...

This reverts commit 7d06fed77b.

This introduced vmem_mutex locking from vmem_map_4k_page()
function called from smp_reinit_ipl_cpu() with interrupts
disabled. While it is a pre-SMP early initcall no other CPUs
running in parallel nor other code taking vmem_mutex on this
boot stage - it still needs to be fixed.
