nfs: Do not convert nfs_idmap_cache_timeout to jiffies

[ Upstream commit cbebc6ef4fc830f4040d4140bf53484812d5d5d9 ]

Since commit 57e62324e469 ("NFS: Store the legacy idmapper result in the
keyring") nfs_idmap_cache_timeout changed units from jiffies to seconds.
Unfortunately sysctl interface was not updated accordingly.

As a effect updating /proc/sys/fs/nfs/idmap_cache_timeout with some
value will incorrectly multiply this value by HZ.
Also reading /proc/sys/fs/nfs/idmap_cache_timeout will show real value
divided by HZ.

Fixes: 57e62324e469 ("NFS: Store the legacy idmapper result in the keyring")
