  loader: g_realloc(p, 0) frees and returns NULL, simplify

Once upon a time, it was decided that qemu_realloc(ptr, 0) should
abort.  Switching to glib retired that bright idea.  A bit of code
that was added to cope with it (commit 3e372cf) is still around.  Bury
it.

See also commit 6528499.

When scsi_bus_legacy_add_drive() produces an error,
we will lose the error message. Using error_report
to report it.

  Log Message:
  -----------
  pc-dimm: Don't check dimm->node when there is non-NUMA config

It should not break memory hotplug feature if there is non-NUMA option.

This patch would also allow to use pc-dimm as replacement for initial memory
for non-NUMA configs.

Note: After this patch, the memory hotplug can work normally for Linux guest OS
when there is non-NUMA option and NUMA option. But not support Windows guest OS
to hotplug memory with no-NUMA config, actully, it's Windows limitation.

  vl: Adjust the place of calling mlockall to speedup VM's startup

If we configure mlock=on and memory policy=bind at the same time,
It will consume lots of time for system to treat with memory,
especially when call mbind behind mlockall.

Adjust the place of calling mlockall, calling mbind before mlockall
can remarkably reduce the time of VM's startup.
