[PATCH] Fix cs firmware loading

[Ryan Mallon]

The function if_cs_poll_while_fw_download returns the number of 
iterations through the loop on success. This value is returned by
the functions if_cs_prog_helper and if_cs_prog_real, however they
should return zero on success. This patch corrects that. An 
alternative would be to just return zero on success from 
if_cs_poll_while_fw_download.
