loadfile: fix crash in some cases of setting --lavfi-complex at runtime 

The somewhat confusing thing is that many filters (including track->dec)
have a public struct, but to free them, you need to free the mp_filter
pointer itself (track->dec->f). The assignment wrote to a dangling
pointer, instead of removing the dangling pointer.

(Other than that, this idiom is actually nice.)
