wifi: ath10k: Fix return value in ath10k_pci_init()

[ Upstream commit 2af7749047d8d6ad43feff69f555a13a6a6c2831 ]

This driver is attempting to register to support two different buses.
if either of these is successful then ath10k_pci_init() should return 0
so that hardware attached to the successful bus can be probed and
supported. only if both of these are unsuccessful should ath10k_pci_init()
return an errno.
