tty/n_gsm: fix bug in tiocmset

Clear bitmask was not inverted before masking modem_tx.

Calling ioctl(fd, TIOCMBIC, TIOCM_RTS) results in:

[  197.430000] pre_modem_tx:	0x00000006
[  197.430000] clear:			0x00000004
[  197.430000] set:			0x00000000
[  197.440000] post_modem_tx:	0x00000004

which is wrong.
