5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Josef Bacik <josef@xxxxxxxxxxxxxx>
[ Upstream commit e41ee44cc6a473b1f414031782c3b4283d7f3e5f ]
This is the last global stat, take it out of the nfsd_stats struct and
make it a global part of nfsd, report it the same as always.
