USB: serial: option: Apply OPTION_BLACKLIST_SENDSETUP also for ZTE MF626

commit 7a89e4cb9cdaba92f5fbc509945cf4e3c48db4e2 upstream.

On https://bugs.launchpad.net/ubuntu/+source/linux/+bug/636091, one of
the cases reported is a big timeout on option_send_setup, which causes
some side effects as tty_lock is held. Looks like some of ZTE MF626
devices also don't like the RTS/DTR setting in option_send_setup, like
with 4G XS Stick W14. The reporter confirms which this it solves the
long freezes in his system.
