aarch64: dump device tree blob before length check

In case the final devicetree blob is too large to fit in the memory
reserved for it, it could be useful to inspect the generated FDT. Move
the code that dumps the FDT to a file before the length check so it will
be written out even if the size is too large.

BUG=None
TEST=crosvm run --dump-device-tree-blob /tmp/fdt # on aarch64

crosvm - The ChromeOS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the ChromeOS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on ChromeOS devices.
