Heiko Carstens 6f367769e3 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
Found:    c0 04 00 00 00 01
Expected: c0 04 00 00 00 00
