Brian Behlendorf 51268f31a8 Remove SELinux enforcing check from init scripts
The default SELinux policy for RHEL and Fedora has been updated
to include ZFS in the list of filesystems which support xattrs.
Therefore, there's no longer a need to detect this in the init
scripts.

# system boot/shutdown. Configuration of which filesystems
# should be mounted is handled by the zfs 'mountpoint' and
# 'canmount' properties. See the zfs(8) man page for details.
# It is also responsible for all userspace zfs services.
