USB-serial fixes for v4.10-rc4

These fixes address a number of issues in the ch341 driver and includes
a partial revert of a change in how we set the line settings that went
into 4.10-rc1 but which turned out to have undesired side effects. This
included deasserting the modem-control lines when configuring the
device, but also prevented a certain class of CH340 devices from working
with the driver.

Included are also two fixes for two minor information leaks in
kl5kusb105 and ch341 due to failures to detect short control transfers.
