Netplay Wii Remote Removal

[rukai]

Finishes Helios' PR #3662, as it hasnt been touched in 10 days and I have fixed a segfault as well.

Fully removes wii remote netplay code from the UI, fixing a segfault when assigning controller ports that is currently present in master.

Yeah. I don't really care and this is less work for me. ;)

Is the DSP Engine still required to match? If so, please add it in the message.

I asked JMC and he said there shouldn't be any settings to manually sync except, memory cards, SD cards and cheats.
I also tested netplay between HLE and LLE recompiler to make sure this wasn't an exception.

Should we note that the DSP ROMs need to be identical between players when DSP LLE is used?

[rukai]

Done.

Can we get this merged soon? This fixes an oversight I had with my initial PR which can cause a crash. LGTM
