Subject: [Resent][PATCH 1/1] inet6: functions shadow global variable

There was no further response on the RFC, I am resending it as a fix.

>>>>>>>>>>>>>>>>>>>>>>>>> Patch v1 (resent) <<<<<<<<<<<<<<<<<<<<<<<<
inet6: local functions shadow global pointer

This renames away a variable clash:
 * ipv6_table[] is declared as a static global table;
 * ipv6_sysctl_net_init() uses ipv6_table to refer/destroy dynamic memory;
 * ipv6_sysctl_net_exit() also uses ipv6_table for the same purpose;
 * both the two last functions call kfree() on ipv6_table.
