s390/entry: Fix setting _CIF_MCCK_GUEST with lowcore relocation
When lowcore relocation is enabled, the machine check handler doesn't
use the lowcore address when setting _CIF_MCCK_GUEST. Fix this by
adding the missing base register.
Fixes: 0001b7bbc53a ("s390/entry: Make mchk_int_handler() ready for lowcore relocation")
