[PATCH] n_r3964 mod_timer() fix

Since Revision 1.10 was released the n_r3964 module wasn't able to receive any
data.  The reason for that behavior is because there were some wrong calls of
mod_timer(...) in the function receive_char (...).  This patch should fix this
problem and was successfully tested with talking to some kuka industrial
robots.
