s390x/tcg: Rework MMU selection for instruction fetches
Instructions are always fetched from primary address space, except when
in home address mode. Perform the selection directly in cpu_mmu_index().
get_mem_index() is only used to perform data access, instructions are
fetched via cpu_lduw_code(), which translates to cpu_mmu_index(env, true).
We don't care about restricting the access permissions of the TLB
entries anymore, as we no longer enter PRIMARY entries into the
SECONDARY MMU. Cleanup related code a bit.
