[PATCH] NFSD: Encode security label as an array

[Kinglong Mee <kinglongmee@gmail.com>]

According at,
https://tools.ietf.org/html/draft-ietf-nfsv4-minorversion2-38#section-12.2.4

"The FATTR4_SEC_LABEL contains an array of two components with the
 first component being an LFS."

Only supports one security label now.
