USBHost: Silence unused variable warnings. 

I removed the initialization of some variables which were never used to
silence GCC warnings.

One of them had me removing the following line from
USBHostMouse::rxHandler():
    int len = int_in->getLengthTransferred();
The variable len is never used again in this method and it doesn't
appear that the int_in->getLengthTransferred() call has any side
effects which would require this extraneous call to remain in the code.
