xpp: bugfix: handle echo_loader errors

Browse Source 
* I/O errors of the device were not propagated up by echo_loader
* As a result, Octasic load failure did not prevented USB renumeration
* Make consistent return values:
  - In our functions: ret < 0 is error
  - In Octasic functions (UINT32): return Octasic error codes
* All error paths prints error messages (so we see how the error propagates)
* Also changed error order testing in init_octasic():
  Return status should be tested before the values of by-reference parameters
