qemu/msix: fix table access issues
Fixes a couple of issues with msix table access: - With misbehaving guests, misaligned 4 byte access could overflow msix table and cause qemu to segfault. Since PCI spec requires host to only issue dword-aligned accesses, as a fix, it's enough to mask the address low bits. - Tables use pci format, not native format, and so we must use pci_[sg]et_long on read/write.
