Hou Tao 532d6b36b2 bpf: Handle in-place update for full LPM trie correctly 
When a LPM trie is full, in-place updates of existing elements
incorrectly return -ENOSPC.

Fix this by deferring the check of trie->n_entries. For new insertions,
n_entries must not exceed max_entries. However, in-place updates are
allowed even when the trie is full.

Fixes: b95a5c4db0 ("bpf: add a longest prefix match trie map implementation")
