virnuma: add nodeset NULL check in virNumaSetupMemoryPolicy

Browse Source 
Introduced by commit c63ef0452b, when nodeset is NULL, validation will
pass in virNumaSetupMemoryPolicy, but virBitmapNextSetBit must ensure
bitmap is not NULL, otherwise that might cause a segmentation fault.
This patch fixes it.
