lpm: fix incorrect reuse of already allocated tbl8

Fixes an initialization issue of 'valid_group' in the delete_depth_small().

When adding an entry to a tbl8, the .valid_group field should always be set,
so that future adds do not accidently find and use this table, thinking it is
currently invalid, i.e. unused, and thereby overwrite existing entries.
