s390/tape: fix MTIOCGET ioctl to report blocksize

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

Remove tape_state from status register and report the drive's current
setting for block size instead as known from other tapes.
Density is not supported so nothing to report here.
