create_fdt sets the fdt variable on RISCVVirtState and this is
used to access the fdt. This reverts a change introduced in
https://github.com/riscv/riscv-qemu/pull/109 which introduced
a redundant return value, overlooking the RISCVVirtState
structure member that made create_fdt inconsistent with the
other RISC-V machines. The other alternative is to change
the other boards to return the fdt. Note: the RISCVVirtState
also contains fdt_size.
