osdep: introduce qemu_anon_ram_free to free qemu_anon_ram_alloc-ed memory

Browse source 
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.
