Jananee Parthasarathy 984d9e522f table: fix crash in LPM IPv6
Unit test table_autotest results in segmentation fault.
Crash occurs in test_table_lpm_ipv6_combined().

Variable 'nht_pos0' used as array subscript is not initialized
in rte_table_lpm_ipv6_entry_add(). It will not be assigned,
if a rule does not exist.

In such case a junk number or invalid array index might result in
segmentation fault due to array out of bounds when
lpm->nht_users is used with such invalid array index.

Fix is to initialize the variables used for array subscript.
