Subject: [PATCH] fastboot: don't die if can't parse boot part size

Don't crash in copy_boot_avb_footer() if bootloaders do not properly
expose the size of the boot partition.

This makes "fastboot flasher boot" usable again on lots of
non-avb-devices, where it has been broken since
I5a5e25fb54dc9d6a2930fda63434968808ffa1f0.
