libxl: fix potential double free in libxlDriverGetDom0MaxmemConf

Browse Source 
Commit 4ab0c959 fixed a memory leak in libxlDriverGetDom0MaxmemConf
but introduced a potential double free of mem_tokens

*** Error in `/usr/sbin/libvirtd': double free or corruption (out):
    0x00007fffc808cfd0 ***

Avoid double free by setting mem_tokens to NULL after calling
virStringListFree.
