[PATCH 1/5] hw/riscv/riscv_hart: free the harts array when the object is finalized

[Damien Hedde]

The array is dynamically allocated by realize() depending on the
number of harts.

This clean-up removes memory leaks which would happen in the
'init->finalize' life-cycle use-case (happening when user creation
is allowed).
