libertas: fix CF firmware loading for some cards
if_cs_poll_while_fw_download() returned the number of iterations remaining on success, which in turn got returned as the value from if_cs_prog_real() and if_cs_prog_helper(). But since if_cs_probe() interprets non-zero return values from firmware load functions as an error, this sometimes caused spurious firmware load failures.
