cifs: show features compiled in as part of DebugData

Browse source 
Fixed the nit pointed out by Jeff.

From: Suresh Jayaraman <sjayaraman@suse.de>
Subject: [PATCH 1/2] cifs: show features compiled in as part of DebugData

This patch adds the features that are compiled in to the CIFS debugging data
as shown below:

	$cat /proc/fs/cifs/DebugData
	Display Internal CIFS Data Structures for Debugging
	---------------------------------------------------
	CIFS Version 1.64
	Features: dfs fscache posix spnego xattr
	Active VFS Requests: 0
	...

This patch provides a definitive way to tell what features are currently
enabled in the running kernel. This could also help debugging.
