cxlflash: Fix to avoid lock instrumentation rejection
When running with lock instrumentation (e.g. lockdep), some of the instrumentation can become disabled at probe time for a cxlflash adapter. This is due to a missing lock registration for the tmf_slock. The fix is to call spin_lock_init() for the tmf_slock during probe. Signed-off-by: Matthew R.
