Fixes use of invalid header data

Fixes a bug when MCUBOOT_VALIDATE_SLOT0 is enabled which caused the
header in Slot 1 to be used for calculating the bootstrap offset. This
bug is masked when MCUBOOT_OVERWRITE_ONLY is not enabled because both
slots have the same header size (usually!). With MCUBOOT_OVERWRITE_ONLY
Slot 1 was erased and the header size would be read as 0xffff resulting
in a jump to the wrong address.
