Fix slot0 validation
commit d930ec69c835b83ba933677d29760ba7605a1158

Validate slot zero before booting
adds a feature to validate slot 0 before booting it. However, there
is an error in the logic, and if the magic number is written to an
invalid value, but not all 0xFF, it will consider any image to be
valid.
Fix this logic so that slot zero is always validated.
MCUBoot is a secure bootloader for 32-bit MCUs. The goal of MCUBoot is to define a common infrastructure for the bootloader, system flash layout on microcontroller systems, and to provide a secure bootloader that enables easy software upgrade.
MCUboot is operating system and hardware independent, and relies on hardware porting layers from the operating system it works with. Currently mcuboot works with both the Apache Mynewt, and Zephyr operating systems, but more ports are planned in the future.
The MCUBoot project was originally taken from the Apache Mynewt operating system, which had secure boot and software upgrade functionality instrinsic to it. Currently development is heads down on a first release of MCUboot that works across both the Zephyr operating system and Apache Mynewt operating system.
