powerpc/pci: Fix regression in powerpc MSI-X
Patch f598282f5145036312d90875d0ed5c14b49fd8a7 exposed a problem in powerpc MSI-X functionality, making network interfaces such as ixgbe and cxgb3 stop to work when MSI-X is enabled. RX interrupts were not being generated. The problem was caused because MSI irq was not being effectively unmasked after device initialization.
