Julian Schroeder 075564ed40 nfsd: destroy percpu stats counters after reply cache shutdown 
[ Upstream commit fd5e363eac77ef81542db77ddad0559fa0f9204e ]

Upon nfsd shutdown any pending DRC cache is freed. DRC cache use is
tracked via a percpu counter. In the current code the percpu counter
is destroyed before. If any pending cache is still present,
percpu_counter_add is called with a percpu counter==NULL. This causes
a kernel crash.
The solution is to destroy the percpu counter after the cache is freed.

Fixes: e567b98ce9a4b (“nfsd: protect concurrent access to nfsd stats counters”)
