Mete Durlu f449395421 s390/hypfs_diag: Diag204 busy loop
When diag204 busy-indiciation facility is installed and diag204 is
returning busy, hypfs diag204 handler now does an interruptable busy
wait until diag204 is no longer busy. If there is a signal pending, call
would be restarted with -ERESTARTSYSCALL, except for fatal signals.
