knfsd: Replace lock_kernel with a mutex in nfsd pool stats.

Browse Source 
lock_kernel() in knfsd was replaced with a mutex. The later
commit 03cf6c9f49 ("knfsd:
add file to export stats about nfsd pools") did not follow
that change. This patch fixes the issue.

Also move the get and put of nfsd_serv to the open and close methods
(instead of start and stop methods) to allow atomic check and increment
of reference count in the open method (where we can still return an
error).
