s390/jump label: add missing jump_label_apply_nops() call

When modules are loaded we want to transform the compile time generated
nops into runtime generated nops. Otherwise the jump label sanity check
will detect invalid code when trying to patch code.

Fixes this crash:

Jump label code mismatch at __rds_conn_create+0x3c/0x720
