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

Scott Mayhewrequested to merge
smayhew/centos-stream-9:RHEL-83435 into main

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.
