file-posix: Fix has_write_zeroes after NO_FALLBACK
If QEMU_AIO_NO_FALLBACK is given, we always return failure and don't even try to use the BLKZEROOUT ioctl. In this failure case, we shouldn't disable has_write_zeroes because we didn't learn anything about the ioctl. The next request might not set QEMU_AIO_NO_FALLBACK and we can still use the ioctl then.
