Merge: NFSv4: Don't check for OPEN feature support in v4.1

MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/6866

JIRA: https://issues.redhat.com/browse/RHEL-83435
Upstream Status: git://git.linux-nfs.org/projects/anna/linux-nfs.git

fattr4_open_arguments is a v4.2 recommended attribute, so we shouldn't
be sending it to v4.1 servers.
