isisd: Stop fulfill MPLS table when SR is disabled

When Segment Routing is disabled, if isisd received LSP with Segment Routing
information, in particular prefix SIDs, it installs corresponding MPLS entries
while it should not as SR is disabled.

This patch adds extra control to verify if SR is enabled or not before
configuring MPLS LFIB & IP FIB with prefix SIDs and adjust SR & TI-LFA
tests accordingly.
