ipvs: check that ip_vs_conn_tab_bits is between 8 and 20
[ Upstream commit 69e73dbfda14fbfe748d3812da1244cce2928dcb ]
ip_vs_conn_tab_bits may be provided by the user through the
conn_tab_bits module parameter. If this value is greater than 31, or
less than 0, the shift operator used to derive tab_size causes undefined
behaviour.
Fix this checking ip_vs_conn_tab_bits value to be in the range specified
in ipvs Kconfig. If not, simply use default value.
Fixes: 6f7edb4881bf ("IPVS: Allow boot time change of hash size")
