m3ua

In compilation of version 2.0.2 there are some WARNING
messages.

In ../config/src/m3ua_lrout.c lines 191 and 301 the
comparison is always TRUE because idx is m3_u8 type
and of course it is always less than
M3_MAX_LOCAL_ROUTE (that is 256). Therefore there are
two endless loops there (Problems when add or delete
routes).

In ../user/src/m3ua_ui.c lines 199, 232, 265, 307, 322
and 344 there is a similar warning but it is not so
critical because the comparison is always FALSE and
the if(...) will not be executed (no problem because
there is no an endless loop).
