[PATCH] staging: gdm72xx: remove unneeded test

[Dan Carpenter]

Obviously, I endorse this idea.  :)  Every out label in this file is
a do-nothing label or a do-everything label, but with bugs.  usb_boot()
should look like:

free_tx_buf:
	kfree(tx_buf);
release_firm:
	release_firmware(firm);

	ret;

If we fail to allocate "tx_buf" then we should release the firmware.
em_download_image() has the same bug as well.
