ospfd: ospf bandwidth handling

if bandwidth is not set from Zebra use speed as bandwidth
for ospf route.

Testing Done:
Verfied over bond which has aggregated speed of all member interfaces,
cost is reflected in ospf route and ip route.
Manually changed interface bandwidth which replaces speed as bw, instead
uses cli entered value as bw, verifid output of ospf route and ip route.
