[IB] Have cq_resize() method take an int, not int*
Change the struct ib_device.resize_cq() method to take a plain integer that holds the new CQ size, rather than a pointer to an integer that it uses to return the new size. This makes the interface match the exported ib_resize_cq() signature, and allows the low-level driver to update the CQ size with proper locking if necessary. No in-tree drivers are exporting this method yet. Signed-off-by: Roland Dreier <rolandd@cisco.com>
