User may not get an error on adding and, therefore, may feel that 
everything went fine, but such queues cannot be used.
At least, that was my observation on increasing the number of poll 
queues from 0 to !0 value.
I continued getting "not supported" error on issuing hipri I/O from 
io_uring. After this patch, the poll queue became usable.
