mlx4_core: Use pci_request_regions()
The old code used two calls to pci_request_region() to get the two BARs for the mlx4 device, for no particularly good reason. Clean up the code a little by converting this to a single call to pci_request_regions(). Signed-off-by: Roland Dreier <rolandd@cisco.com>
