gNFS: Allow reading ACLs even without read permissions on the file.
When root-squash is enabled or when no permissions are given to
a file, NFS threw permission errors. According to the kernel-nfs
behaviour, no permissions are required to read ACLs.
When no ACLs are set, the system call sys_lgetxattr fails and
returns a ENODATA error. This translates to ESERVERFAULT error
in NFS. Fuse makes an exception to this error and returns a success
case. Similar changes are made here to achieve the expected behaviour.
