[PATCH] USB-SERIAL cp210x: Remove double usb_control_msg fromcp210x_set_config

[Michael Brunner]

This patch removes a double usb_control_msg that sets the cp210x
configuration registers a second time when calling cp210x_set_config.
For data sizes >2 the second write gets corrupted.
The patch has been created against 2.6.34-rc1, but all cp210x driver
revisions are affected.
