Fix a bug introduced in rev. 1.69, when implementing the 

fallback from each programmer's paged_load() or paged_write()
method, respectively.  The return value needs to be checked for
being greater or equal than 0 rather equal to 0 in order to
assume the operation has been successful.

Fixes bug #18489: avrdude is too slow (20 byte/s)
