usbreset: fix swapped vendor and product ID in help/manpage

usbreset help and manpage describe the reset by product and vendor IDs
as PPPP:VVVV, a completly non-standard way to identify USB devices. In
practice, the value is correctly parsed in the standard USB format,
which is vendor ID followed by product ID (VVVV:PPPP).

This patch corrects both help message and manpage to reflect the correct
format. It also changes text to mention vendor before product to prevent
further confusion.
