Subject: [PATCH] Revert "In kernel version 6.8 and above, nfsd has deprecated
 the CONFIG_NFSD_LEGACY_CLIENT_TRACKING option, and in kernel 6.12, if
 CONFIG_NFSD_LEGACY_CLIENT_TRACKING is still enabled, the following kernel
 panic may occur:"

This reverts commit b7c4407c296d2fcde087863f7580bc9e97cb89ec.
