trunks: Do not invoke USB clear functions, unless necessary

Invoking these functions in case USB was not initialized seems to be
working fine in the chroor, but causes lock ups when using libftdi in
Ubuntu (as opposed to libftdi1).

Add a filed to the MPSSE structure to keep track of the interface
creation progress. In fact this field was present in the original
usbmpsse package, but was dropped at some point along the way.

TEST=program does not crash on start any more, connects to the UDB
