This patch remove the function klsi_105_tiocmset which was only
returning -EINVAL. It also removes the function prototype and
the .tiocmset entry in the struct usb_serial_driver.
Verified by compilation only.

Changes from V1:
- remove the function klsi_105_tiocmset instead of simplifying it
- remove the function prototype
- remove the .tiocmset entry in the struct usb_serial_driver
- update commit message and subject
