USB: serial: kobil_sct: fix TIOCMBIS and TIOCMBIC
commit d432df758f92c4c28aac409bc807fd1716167577 upstream.
Asserting or deasserting a modem control line using TIOCMBIS or TIOCMBIC
should not deassert any lines that are not in the mask.
Fix this long-standing issue dating back to 2003 when the support for
these ioctls was added with the introduction of the tiocmset() callback.
