[S390] cio: commit all pmcw changes.
Sometimes we change the pmcw configuration but don't call msch to transmit these changes to the channel subsystem. The patch fixes this by calling cio_commit_config in such cases. Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
