        sys/nfs/nfs_vnops.c: revision 1.325

NFS client: fix interop with macOS 14 servers.

Symptom: a bunch of "Cannot open `.' (Invalid argument)".
thorpej@ analysis and fix: on the first request to read a given
directory, make sure READDIR and READDIRPLUS cookie verifiers are
being set to 0. This is in RFC1813 and macOS must have gotten
stricter about it.

Verified on 10.0_RC1/aarch64 to fix the reproducers in PR kern/57691 as
well as the original use case in which I met the bug: pkg_rr once again
runs to completion.
