s390/qeth: fix SETIP command handling
send_control_data() applies some special handling to SETIP v4 IPA
commands. But current code parses *all* command types for the SETIP
command code. Limit the command code check to IPA commands.
Fixes: 5b54e16f1a54 ("qeth: do not spin for SETIP ip assist command")
