net: Set rtm_table to RT_TABLE_COMPAT for ipv6 for tables > 255

Browse Source 
[ Upstream commit 97f0082a0592212fc15d4680f5a4d80f79a1687c ]

Set rtm_table to RT_TABLE_COMPAT for ipv6 for tables > 255 to
keep legacy software happy. This is similar to what was done for
ipv4 in commit 709772e6e065 ("net: Fix routing tables with
id > 255 for legacy software").
