staging: fwserial: fix TIOCSSERIAL jiffies conversions
commit 7a3791afdbd5a951b09a7689bba856bd9f6c6a9f 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.
