[PATCH] firewire: core: put GFP_ATOMIC back in fw_node_create()

[Dan Carpenter]

This was recently changed from GFP_ATOMIC to GFP_KERNEL, but it
needs to be GFP_ATOMIC so change it back.  The problematic
call tree is:

fw_core_handle_bus_reset() <- spin_lock_irqsave(&card->lock, flags);
-> build_tree()
   -> fw_node_create() <- sleeping allocation

Fixes: 06f45435d985 ("firewire: core: obsolete usage of GFP_ATOMIC at building node tree")
