Fixes an initialization issue of 'valid_group' in the delete_depth_small function.
In this function, use new rte_lpm_tbl8_entry we call A to replace the old rte_lpm_tbl8_entry. But the valid_group do not set VALID, so it
will be INVALID.
Then when adding a new route which depth is > 24,the tbl8_alloc() function will search the rte_lpm_tbl8_entrys to find INVALID
valid_group, and it will return the A to the add_depth_big function, so A's data is overridden.
