Erm, no this wrong, very very wrong, you're freeing the buffer were using to
store the actual
usb data in here, while the usb transfers are still being used (are being
created to get
used) not good.
This will get freed when the actual transfer gets free-ed through calling
usbredirhost_free_transfer(), specifically by this line in that function:
free(transfer->transfer->buffer);

This leak fix is correct, no need for the if though, free(NULL) is a nop. I've
pushed this
to the usbredir git repo.
