exec: Eliminate qemu_ram_free_from_ptr()

Browse source 
Replace qemu_ram_free_from_ptr() with qemu_ram_free().

The only difference between qemu_ram_free_from_ptr() and
qemu_ram_free() is that g_free_rcu() is used instead of
call_rcu(reclaim_ramblock). We can safely replace it because:

* RAM blocks allocated by qemu_ram_alloc_from_ptr() always have
  RAM_PREALLOC set;
* reclaim_ramblock(block) will do nothing except g_free(block)
  if RAM_PREALLOC is set at block->flags.
