s390/cio: make sch->lock spinlock pointer a member
The lock member of struct subchannel used to be a spinlock, but became
a pointer to a spinlock with commit 2ec2298412e1 ("[S390] subchannel
lock conversion."). This might have been justified back then, but with
the current state of affairs, there is no reason to manage a separate
spinlock object.
Let's simplify things and pull the spinlock back into struct subchannel.
