USB: serial: mct_u232: clean up urb->status usage
This done in anticipation of removal of urb->status, which will make that patch easier to review and apply in the future. Cc: <linux-usb-devel@lists.sourceforge.net> Cc: Wolfgang Grandegger <wolfgang@ces.ch> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
