net: mvpp2: prevent buffer overflow in mvpp22_rss_ctx()
The "rss_context" variable comes from the user via ethtool_get_rxfh().
It can be any u32 value except zero. Eventually it gets passed to
mvpp22_rss_ctx() and if it is over MVPP22_N_RSS_TABLES (8) then it
results in an array overflow.
Fixes: 895586d5dc32 ("net: mvpp2: cls: Use RSS contexts to handle RSS tables")
