Subject: [PATCH net-next 1/2] net/ipv6: Remove unnecessary pr_debug() logs

In the ipv6 system, we have some logs basically dumping the name of the
function that is being called. This is not ideal, since ftrace give it
to us "for free". Moreover, checkpatch is not happy when touching that
code:

	WARNING: Unnecessary ftrace-like logging - prefer using ftrace

Remove debug functions that only print the current function name.
