memory: fix segv on qemu_ram_free(block=0x0)
Since f1060c55bf1377b4, the pointer is directly passed to
qemu_ram_free(). However, on initialization failure, it may be called
with a NULL pointer. Return immediately in this case.
This fixes a SEGV when memory initialization failed, for example
permission denied on open backing store /dev/hugepages, with -object
memory-backend-file,mem-path=/dev/hugepages.
Program received signal SIGSEGV, Segmentation fault.
