RTEMS Stack Checker Report Bad Access When Not Enabled

Description

The RTEMS stack checker reporting function can be called without the stack checker infrastructure being enabled. This causes a bad access to 0x0 because the static interrupt stack checker data remains null instead of being initialized by rtems_stack_checker_begin_extension. The actual failure occurs in Stack_check_Find_high_water_mark while searching for U32_PATTERN.

This was found when the trailing D was left off of the CONFIGURE_STACK_CHECKER_ENABLED define in a test program.
