Subject: [ 071/150] PCI: Fix PCI Express Capability accessors for PCI_EXP_FLAGS

3.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Williamson <alex.williamson@...hat.com>

commit 969daa349f4821a02936af7202b51a9affc7b6da upstream.

PCI_EXP_FLAGS_TYPE is a mask, not an offset.  Fix it.

Previously, pcie_capability_read_word(..., PCI_EXP_FLAGS, ...) would
fail.
