[PATCH] s390: chps[] array too short

The chps[] array in struct channel_subsystem is one too short; therefore the
code doesn't realize the chpid ff is already known.  When several devices on
chpid ff become available, the message "new_channel_path: could not register
ff" is displayed for every device but the first one.
