Subject: [PATCH] net/ipv6/sysctl_net_ipv6.c: fix sparse warnings

Fix two sparse warnings in net/ipv6/sysctl_net_ipv6.c.

Both sparse warnings are as follows:

  warning: symbol 'ipv6_table' shadows an earlier one

ipv6_sysctl_net_init() and ipv6_sysctl_net_exit() both use the same
symbol name for the struct ctl_table used to do the 
{register/unregister}_net_sysctl_table().

The static symbol is only used in ipv6_sysctl_register() for the
struct ctl_table used to do the register_net_sysctl_rotable().

Rename the static symbol to ipv6_rotable to remove the sparse warnings.
