s390/vmlinux.lds.S: Move ro_after_init section behind rodata section
The .data.rel.ro and .got section were added between the rodata and
ro_after_init data section, which adds an RW mapping in between all RO
mapping of the kernel image:

Move the ro_after_init data section again right behind the rodata
section to prevent interleaving RO and RW mappings:
