powerpc/vas: Fix potential NULL pointer dereference
(!ptr && !ptr->foo) strikes again. :)
The expression (!ptr && !ptr->foo) is bogus and in case ptr is NULL,
it leads to a NULL pointer dereference: ptr->foo.
Fix this by converting && to ||
This issue was detected with the help of Coccinelle, and audited and
fixed manually.
