tty: max3100: remove unused variable rts and remove unused assignment
Variable rts is being assigned but it is never read, hence it can be
removed. The assignment to param_new to zero is redundant as it is
being updates a few statements later, so remove this redundant
assignment. Cleans up two clang warnings:
drivers/tty/serial/max3100.c:277:3: warning: Value stored to 'rts'
is never read
drivers/tty/serial/max3100.c:439:2: warning: Value stored to 'param_new'
is never read
