s390/extable: Remove EX_TABLE macros and fallback extable search

Now that all exception table entries point to the faulting instruction,
rename all EX_TABLE* macros to EX_TABLE_INSN* and remove the
EX_TABLE_INSN* aliases.

Also remove the fallback extable search via instruction_pointer() which
was only needed to handle the old EX_TABLE entries that pointed to the
instruction after the faulting instruction.

Add a comment above the EX_TABLE_INSN macros that documents the usage
rule and describe the difference to the previous EX_TABLE macros. This
might be helpful in case of backporting to old kernels.
