An error in e333f3bbefe3 left the nfsd_acl_program->pg_vers array empty,
which effectively turned off the server's support for NFSv3 ACLs.

Fixes: e333f3bbefe3 "nfsd: Allow containers to set supported nfs versions"

Kinda wondering if it says something that server NFSv3 ACL support was
off in 5.2 and 5.3 and nobody noticed.  (At least I don't recall any
reports.)
