From: Youssef Samir <quic_yabdu...@quicinc.com> [ Upstream commit 8685520474bfc0fe4be83c3cbfe3fb3e1ca1514a ]
During the initialization of the qaic device, pci_select_bars() is used to fetch a bitmask of the BARs exposed by the device. On devices that have Virtual Functions capabilities, the bitmask includes SR-IOV BARs. Use a mask to filter out SR-IOV BARs if they exist.
