Revert "selinux: consider filesystem subtype in policies"

This reverts commit 102aefdda4d8275ce7d7100bc16c88c74272b260.

Explanation from Eric Paris:

	SELinux policy can specify if it should use a filesystem's
	xattrs or not.  In current policy we have a specification that
	fuse should not use xattrs but fuse.glusterfs should use
	xattrs.  This patch has a bug in which non-glusterfs
	filesystems would match the rule saying fuse.glusterfs should
	use xattrs.  If both fuse and the particular filesystem in
	question are not written to handle xattr calls during the mount
	command, they will deadlock.

	I have fixed the bug to do proper matching, however I believe a
	revert is still the correct solution.  The reason I believe
	that is because the code still does not work.  The s_subtype is
	not set until after the SELinux hook which attempts to match on
	the ".gluster" portion of the rule.  So we cannot match on the
	rule in question.  The code is useless.
