rtos/riot: fix out-of-bounds writes when target is corrupted

This protects against out-of-bounds writes when the memory
of RIOT's scheduler is corrupted.
This memory can be corrupted because of:
 - Programming errors
 - The scheduler not yet having been initialised
 - An incorrect symbol file being used during debugging.

This error can result in OpenOCD segfaulting. Valgrind was
used to find the approximate location of the error.
