Rakesh BB e33ffd5e8c refactor: harmonize AS key BIT_STRING macro 
Replace duplicated KENB_STAR_TO_BIT_STRING and
KGNB_STAR_TO_BIT_STRING macros with the unified
AS_KEY_STAR_TO_BIT_STRING helper across X2AP,
XNAP, M2AP, and M3AP code paths.

Also switch allocation to calloc_or_fail for
safer memory handling.

No functional change intended.
