ipvs: Remove {Enter,Leave}Function

Remove EnterFunction and LeaveFunction.

These debugging macros seem well past their use-by date.  And seem to
have little value these days. Removing them allows some trivial cleanup
of some exit paths for some functions. These are also included in this
patch. There is likely scope for further cleanup of both debugging and
unwind paths. But let's leave that for another day.

Only intended to change debug output, and only when CONFIG_IP_VS_DEBUG
is enabled. Compile tested only.
