osdep: introduce qemu_anon_ram_free to free qemu_anon_ram_alloc-ed memory
We switched from qemu_memalign to mmap() but then we don't modify qemu_vfree() to do a munmap() over free(). Which we cannot do because qemu_vfree() frees memory allocated by qemu_{mem,block}align. Introduce a new function that does the munmap(), luckily the size is available in the RAMBlock.
