ipv6: fix array index in ip6_mc_add_src()

Browse Source 
[ Upstream commit 78d50217ba ]

Convert array index from the loop bound to the loop index.

And remove the void type conversion to ip6_mc_del1_src() return
code, seem it is unnecessary, since ip6_mc_del1_src() does not
use __must_check similar attribute, no compiler will report the
warning when it is removed.

v2: enrich the commit header
