USB: ftdi-elan: Always pass usb_bulk_msg() a timeout in milliseconds.

Browse source 
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.
