[PATCH] selinux: disable setxattr on mountpoint labeled filesystems



This patch disables the setting of SELinux xattrs on files created in
filesystems labeled via mountpoint labeling (mounted with the context=
option).  selinux_inode_setxattr already prevents explicit setxattr from
userspace on such filesystems, so this provides consistent behavior for
file creation.
