Ganesh Ajjanagadde 301c2784b3 lavfi/vf_overlay: fix memory leaks

Recent commits 6aaac24d72a7da631173209841a3944fcb4a3309 and
3835554bf8ed78539a3492c239f979c0ab03a15f made progress towards cleaning
up usage of the formats API, and in particular fixed possible NULL pointer
dereferences.

This commit addresses the issue of possible resource leaks when some intermediate
call fails.

Tested with valgrind --leak-check=full --show-leak-kinds=all, and manual simulation
of malloc/realloc failures.

Fixes: CID 1338327.
