[Committed] S/390: PR57609 fix - use next_active_insn instead of next_real_insn

[Andreas Krebbel]

Hi,

the patch replaces next_real_insn with next_active_insn when checking
for JUMP TABLE insns.

This fixes ESA mode bootstrap on s390 which broke with r197266.

Comitted to mainline

Bye,

-Andreas-
