Aswin Karuvally 1b02c86171 s390/qeth: Make hw_trap sysfs attribute idempotent
Update qeth driver to allow writing an existing value to the "hw_trap"
sysfs attribute. Attempting such a write earlier resulted in -EINVAL.
In other words, make the sysfs attribute idempotent.

After:
    $ cat hw_trap
    disarm
    $ echo disarm > hw_trap
    $
