Respect that status property when parsing fstab from device tree 

For an fstab entry in device tree, fs_mgr now honors the status property
as done by linux. i.e. the node (in this case, the fstab entry) is
enabled if status is not set, "ok" or "okay". For every other value, the
node is considered as disabled.
