net: add a route cache full diagnostic message
commit 22c2ad616b74f3de2256b242572ab449d031d941 upstream.
In some testing scenarios, dst/route cache can fill up so quickly
that even an explicit GC call occasionally fails to clean it up. This leads
to sporadically failing calls to dst_alloc and "network unreachable" errors
to the user, which is confusing.
This patch adds a diagnostic message to make the cause of the failure
easier to determine.
