[PATCH 16/35] staging: lustre: llite: support SELinux context labelling

[James Simmons <jsimmons@infradead.org>]

From: Andrew Wellington <andrew.wellington@anu.edu.au>

SELinux contexts are applied by the kernel if mount options are
not binary. As we don't use any binary mount options in Lustre,
remove the binary mount option flag.
