eptri: clear proper endpoint when opening IN port 

When opening a USB port, we ensure the buffer is NULL and has
a length of 0.

Due to a mistake in specifying the endpoint type, we never actually
cleared the value when opening an IN endpoint.  This patch fixes
the comparison when opening an IN endpoint.

This fixes issue #218.
