do_boot_mode() copies the firmware payload, excluding its four-byte prefix,
into a fixed 15.5 KiB staging buffer. check_fw_sanity() already proves that
the image contains its seven-byte header and validates the declared image
length and checksum, but it does not impose this boot-mode destination
limit.
Reject images whose payload does not fit before allocating and filling the
staging buffer.
