bug: v/84212
Rootcase: The lightweight sched_note_printf function in the NuttX backend does not
perform NULL safety checks for the %s format specifier. Passing a NULL pointer from
hsm_get_state_name leads to a NULL pointer dereference, triggering a data abort
exception on systems with memory protection (MMU/MPU) and causing a system crash.
Solution: This commit addresses the issue by modifying the HSM_SAFE_NAME macro to
use the ternary operator. It now explicitly returns the "None" string literal when
hsm_get_state_name returns NULL, guaranteeing that a valid, non-null C-string is always
passed to the logging function.
