msm_fb: display: add wfd suspend/resume to early suspend

wfd on/off was handled by fb_on/fb_close which are called from video
or userspace side. However, this is not the case for this branch. mdp
driver has to register wfd for suspend to make sure proper panel
on/off happen.

Use shared workqueue to delay the update of backlight after
a first valid frame is displayed on the panel. This avoids any
transients being displayed during resume.

netfilter: xt_qtaguid: fix error exit that would keep a spinlock.

qtudev_open() could return with a uid_tag_data_tree_lock held
when an kzalloc(..., GFP_ATOMIC) would fail.
Very unlikely to get triggered AND survive the mayhem of running out of mem.

netfilter: xt_qtaguid: Allow tracking loopback

In the past it would always ignore interfaces with loopback addresses.
Now we just treat them like any other.
This also helps with writing tests that check for the presence
of the qtaguid module.
