Both usages of authenticate_image treat the result code as a simple binary. The command line usage of authenticate_image directly returns the result code of authenticate_image as a success/failure code.
Right now when calling hab_auth_img and test the result code in a shell a passing hab_auth_img will appear to the shell as a fail.
The first step in fixing this behaviour is to fix-up the result code return by authenticate_image() itself, subsequent patches fix the interpretation of authenticate_image so that zero will return CMD_RET_SUCCESS and non-zero will return CMD_RET_FAILURE.
The first step is fixing the return type in authenticate_image() so do that now.
