USB: usbfs: properly clean up the as structure on error paths

commit ddeee0b2eec2a51b0712b04de4b39e7bec892a53 upstream.

I notice that the processcompl_compat() function seems to be leaking the
'struct async *as' in the error paths.

I think that the calling convention is fundamentally buggered. The
caller is the one that did the "reap_as()" to get the as thing, the
caller should be the one to free it too.

Freeing it in the caller also means that it very clearly always gets
freed, and avoids the need for any "free in the error case too".
