If /chosen was missing, chosen_offset would never get updated with the new
/chosen node. This would cause fdt_setprop_u32 to fail. This patch fixes
this by setting chosen_offset. In addition, log any errors from setting
boot-hartid as well.
Fixes: 177c53fe6c6 ("riscv: Move all fdt fixups together")

I have not actually tested this (nor observed the original failure). But this
seemed buggy from inspection.

I think the correct commit id to fix is:
commit 5370478d1c7afb8b2a8a0a00b31ff97c3a2c0451 ("riscv: Add boot
hartid to device tree")
