Daniel Borkmann 976d28bfd1 bpf: don't enable preemption twice in smap_do_verdict 
In smap_do_verdict(), the fall-through branch leads to call
preempt_enable() twice for the SK_REDIRECT, which creates an
imbalance. Only enable it for all remaining cases again.

Fixes: 174a79ff95 ("bpf: sockmap with sk redirect support")
