drivers: input: accuracy filter control cleanup by franco, but I left
out the tweaks.

I assume the temporary change to a multi-threaded workqueue (one per
core) is what was causing touch issues for some users. Glad to see this
reverted back in this commit as I was expecting this to be the culprit
when I came back to study the first commit.

Netfilter: per Google's kernel devs, this was a change from mainline
linux and we should not have CONFIG_NF_CONNTRACK_SIP/CONFIG_NF_NAT_SIP
turned on in the config. Testing is under way.
