This restores the original behaviour before the block callbacks were introduced. Allow the drivers to do binding of block always, no matter if the NETIF_F_HW_TC feature is on or off.

Currently the bridge device doesn't generate any notifications upon vlan modifications on itself because it doesn't use the generic bridge notifications. With the recent changes we know if anything was modified in the vlan config thus we can generate a notification when necessary for the bridge device so add support to br_ifinfo_notify() similar to how other combined functions are done - if port is present it takes precedence, otherwise notify about the bridge. I've explicitly marked the locations where the notification should be always for the port by setting bridge to NULL. I've also taken the liberty to rearrange each modified function's local variables in reverse xmas tree as well.

Specifically, per Andrea the scenario is "A return to userland to repeat the page fault later with a VM_FAULT_NOPAGE retval (potentially after handling any pending signal during the return to userland). The return to userland is identified whenever FAULT_FLAG_USER|FAULT_FLAG_KILLABLE are both set in vmf->flags" However, since commit a3c4fb7c ("x86/mm: Fix fault error path using unsafe vma pointer") there is a vma_pkey() read of vma->vm_flags after that point, which can thus become use-after-free. Fix this by moving the read before calling handle_mm_fault().
