s390/kprobes: Remove custom insn slot allocator

Browse source

Since commit c98d2ecae0 ("s390/mm: Uncouple physical vs virtual address
spaces") the kernel image and module area are within the same 4GB area.

This eliminates the need of a custom insn slot allocator for kprobes within
the kernel image, since standard module_alloc() allocated pages are
sufficient for PC relative instructions with a signed 32 bit offset.
