USB: ftdi-elan: Always pass usb_bulk_msg() a timeout in milliseconds.
The kernel doc for usb_bulk_msg() says the timeout for a bulk message should be specified in milliseconds. The ftdi-elan driver converts milliseconds to jiffies before passing the timeout to usb_bulk_msg(). This is mostly harmless, since it will just lead to very long timeouts, but was obviously not the intent of the original author.
