s390/tape: Fix device driver name (2026-02-19 15:28:00 +0100)

----------------------------------------------------------------
s390 fixes for 7.0 merge window

- Make KEXEC_SIG available again for CONFIG_MODULES=n

- The s390 topology code used to call rebuild_sched_domains() before common
code scheduling domains were setup. This was silently ignored by common
code, but now results in a warning. Address by avoiding the early call

- Convert debug area lock from spinlock to raw spinlock to address lockdep
warnings

- The recent 3490 tape device driver rework resulted in a different device
driver name, which is visible via sysfs for user space. This breaks at
least one user space application. Change the device driver name back to
its old name to fix this
