mpsse: Always perform a general reset of the MPSSE in mpsse_open()

Per AN_135 FTDI MPSSE Basics Version 1.1, section 4.2 step 7.
http://www.ftdichip.com/Support/Documents/AppNotes/AN_135_MPSSE_Basics.pdf

This allows to stop and restart OpenOCD reliably, without needing
to power cycle the interface.
