auto_init: use full hash to configure radio address

Since the 4-byte CPU ID on native is in most cases generated from the 2-byte
PID of the native process, choosing the lower half of the hash of the CPU ID to
set the radio address led to always setting it to the hash of 0 in this
cases. This changes it to use both halves of the hash and taking the
modulus so this corner cases can be avoided.
auto_init: reduce scope of iface

lint: fix unassignedVariable warnings in stm32f1
lint: fix unusedVariable warnings
 lint: fix redundantAssignment warnings
lint: fix unreadVariable warnings
lint: fix variableScope warnings
lint: fix invalidPrintfArgType_sint  warning
lint: fix uselessAssignmentPtrArg

    I've chosen to supress instead of removing the assignment because it looks
    like it may introduce a timing bias in the crypto code otherwise.
