fix(hardsubx): Fix crash in _dinit_hardsubx due to incorrect freep usage

Browse Source 
The freep() function expects a pointer-to-pointer (void**) so it can
dereference, free, and NULL-out the pointer. The code was passing
lctx->dec_sub directly instead of &lctx->dec_sub.

This caused freep to interpret the first 8 bytes of the cc_subtitle
struct as a pointer and attempt to free() it, resulting in a crash
(SIGABRT/exit code 134) in the memory allocator.

Fixes Test 241 (Hardsubx) crash on Sample Platform.
