[S390] cio: fix chsc_chp_vary
The functions called by chsc_chp_vary operate on pointers to channel path ids not channel path links. (This worked by chance since the id is the first member of the link structure) Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
