tools: imx8image: Fix handle leak

The handle "fd" was created in imx8image.c:249 by calling the "fopen"
 function and is lost in imx8image.c:282.
 Should close the 'fd' file descriptor before exiting the
 parse_cfg_file(image_t *param_stack, char *name) function.

Fixes: a2b96ece5be1 ("tools: add i.MX8/8X image support")
