dm cache: handle kmalloc failure allocating background_tracker struct
Currently there is no kmalloc failure check on the allocation of
the background_tracker struct in btracker_create(), and so a NULL return
will lead to a NULL pointer dereference. Add a NULL check.
Detected by CoverityScan, CID#1416587 ("Dereference null return value")
Fixes: b29d4986d ("dm cache: significant rework to leverage dm-bio-prison-v2")
