 Log Message:
 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.
