Dave Jiang 673d812d30 dmaengine: idxd: fix wq slot allocation index check 
The sbitmap wait and allocate routine checks the index that is returned
from sbitmap_queue_get(). It should be idxd >= 0 as 0 is also a valid
index. This fixes issue where submission path hangs when WQ size is 1.

Fixes: 0705107fcc ("dmaengine: idxd: move submission to sbitmap_queue")
