ath10k: don't assume this is a PCI dev in generic code

Browse source

Not all devices using this driver are backed by a PCI device, so it's
not fair to assume 'to_pci_dev()' is valid. Fortunately, we only were
using this to convert straight back to a bare 'device', which means we
were only doing no-op pointer arithmetic, and not actually accessing
potentially out-of-bounds memory. But this is still bad practice.

Just use 'ar->dev' directly, since that's really all we're looking for.
