s390: remove superfluous tpi from wait_cons_dev wait_cons_dev waits for a particular subchannel to complete an I/O. It is not necessary to use tpi to get the subchannel id as it is already known. This avoids changes to the interrupt subclass mask and allows to remove the lock & unlock of the subchannel lock. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
