Alexander Egorenkov 3b90954419 s390/dump: fix copying to user-space of swapped kdump oldmem 
This commit fixes a bug introduced by commit e9e7870f90 ("s390/dump:
introduce boot data 'oldmem_data'").
OLDMEM_BASE was mistakenly replaced by oldmem_data.size instead of
oldmem_data.start.

This bug caused the following error during kdump:
kdump.sh[878]: No program header covering vaddr 0x3434f5245found kexec bug?

Fixes: e9e7870f90 ("s390/dump: introduce boot data 'oldmem_data'")
