Subject: igb_uio: fix build with kernel older than 3.3

igb_uio: fix build with kernel older than 3.3

Since Linux commit fb51ccbf217 (PCI: Rework config space blocking services),
the functions pci_(un)block_user_cfg_access are replaced by
pci_cfg_access_(un)lock.

The compatibility with older functions was broken since commit 399a3f0db8b0
(igb_uio: fix IRQ mode handling).
