Make it more obvious that OVS_KEY_ATTR_MPLS may be an array

Browse Source 
Note that OVS_KEY_ATTR_MPLS may be an array of ovs_key_mpls
and that the acceptable length may be restricted by the implementation.

Currently the user-space datapath and proposed kernel datapath
implementation restrict the length to a single element.

Also update the mpls_top_lse name of the element of struct ovs_key_mpls,
as it is an array of LSEs and thus not necessarily just the top LSE.
