drm/msm: return -EFAULT if copy_from_user() fails
copy_from_user_inatomic() is actually a local function that returns
-EFAULT or positive values on error. Otherwise copy_from_user() returns
the number of bytes remaining to be copied. We want to return -EFAULT
here.
I removed an unlikely() because we just did a copy_from_user()
so I don't think it can possibly make a difference.
