[PATCH] Synclink.c cleanup

[Eric Sesterhenn <snakebyte@gmx.de>]

hi,

coverity was lead to two false bug reports ( #782, #783 )
where the driver checked if tty was valid, when it should
always be. All cases which I found call these functions
by tty->driver->mgsl_write(...) so tty has to be valid.
This patch removes those two checks.
