USB: kaweth.c: use GFP_ATOMIC under spin_lock
[ Upstream commit e4c7f259c5be99dcfc3d98f913590663b0305bf8 ]
The problem is that we call this with a spin lock held. The call tree
is:
kaweth_start_xmit() holds kaweth->device_lock.
-> kaweth_async_set_rx_mode()
-> kaweth_control()
-> kaweth_internal_control_msg()
The kaweth_internal_control_msg() function is only called from
kaweth_control() which used GFP_ATOMIC for its allocations.
