sch_gred: should not use GFP_KERNEL while holding a spinlock
[ Upstream commit 3f1e6d3fd37bd4f25e5b19f1c7ca21850426c33f ]
gred_change_vq() is called under sch_tree_lock(sch).
This means a spinlock is held, and we are not allowed to sleep in this
context.
We might pre-allocate memory using GFP_KERNEL before taking spinlock,
but this is not suitable for stable material.
