unpack_loose_rest(): simplify error handling

Inflating a loose object is considered successful only if we got Z_STREAM_END and there were no more bytes. We check both of those conditions and return success, but then have to check them a second time to decide which error message to produce. I.e., we do something like this: if (!error_1 && !error_2) ...return success... if (error_1) ...handle error1... else if (error_2) ...handle error2... ...common error handling... This repetition was the source of a small bug fixed in an earlier commit (our Z_STREAM_END check was not the same in the two conditionals). Instead we can chain them all into a single if/else cascade, which avoids repeating ourselves: if (error_1) ...handle error1... else if (error_2) ...handle error2.... else ...return success... ...common error handling...
