tty: moxa: fix TIOCSSERIAL jiffies conversions

Browse source 
commit 6e70b73ca5240c0059a1fbf8ccd4276d6cf71956 upstream.

The port close_delay parameter set by TIOCSSERIAL is specified in
jiffies, while the value returned by TIOCGSERIAL is specified in
centiseconds.

Add the missing conversions so that TIOCGSERIAL works as expected also
when HZ is not 100.
