Details:

As reported on [https://github.com/arduino/Arduino/issues/8198] , 
`patch #8924: Enable TPI for usbtiny` broke the functionality of such
programmer for non TPI targets.

The refactor included reworking `usbtiny_initialize`, which used to call
`pgm->program_enable` once and, in case of failure, reset the programmer and
call it again.

The new code considers the return code successful if >=0, so the first failure
is not reported and the programmer is not being reset.

The attached patch restores the previous behaviour by checking if
`pgm->program_enable() == 0`
