net: ircomm, cleanup TIOCGSERIAL
In ircomm_tty_get_serial_info, struct serial_struct is memset to 0 and
then some members set to 0 explicitly.
Remove the latter as it is obviously superfluous.
And remove the retinfo check against NULL. copy_to_user will take care
of that.
Part of hub6 cleanup series.
