net: usb: pegasus: Check the return value of get_geristers() and friends;

Browse source

Certain call sites of get_geristers() did not do proper error handling.  This
could be a problem as get_geristers() typically return the data via pointer to a
buffer.  If an error occurred the code is carelessly manipulating the wrong data.
