[PATCH] ath10k: fix system hang at qca99x0 probe on x86 platform

[Adrian Chadd]

Some more test hardware arrived on Friday, so I'll whack a peregrine
v2 NIC in this afternoon and test out my changes.

I'll send a pull request with the DMA32 changes today or tomorrow.

(If someone would like to send me some beeliner/cascade hardware or
arrange something to be picked up in San Jose then I can test on that,
otherwise it'll have to wait; I don't have easy access to anything
else besides dakota and that is being used for other bring-up
activities atm.)
