nfsd: make use of warning provided by refcount_t
refcount_t, by design, checks for unwanted situations and provides
warnings. It is rarely useful to have explicit warnings with refcount
usage.
In this case we have an explicit warning if a refcount_t reaches zero
when decremented. Simply using refcount_dec() will provide a similar
warning and also mark the refcount_t as saturated to avoid any possible
use-after-free.
This patch drops the warning and uses refcount_dec() instead of
refcount_dec_and_test().
