potentially fix freeze with fast FMOD bank loading

[wuke32767]

i'm not too sure how did it work

[wuke32767]

so i understood it:
someone is accessing the content map in the main thread while audio is loading, so main thread is blocked;
main thread is blocked, so fmod can't be updated, and requested bank can't be loaded.

EDIT: i found it in the document. https://www.fmod.com/docs/2.00/api/studio-guide.html#studio-system-processing

this pr unlocks content map when waiting audio loading.

It looks promising even though I could not repro the issue without forcing it via extra code.
My only concern is calling PostProcessBank outside of the lock. It used to be called in it so I'd say the safe bet is to keep it that way.

LGTM.
