Subject: [PATCH] net/ipv4: Use non-atomic allocation of udp offloads structure
 instance

Since udp_add_offload() can be called from non-sleepable context e.g
under this call tree from the vxlan driver use case:

  vxlan_socket_create() <-- holds the spinlock
  -> vxlan_notify_add_rx_port()
     -> udp_add_offload()  <-- schedules

we should allocate the udp_offloads structure in atomic manner.

Fixes: b582ef0 ('net: Add GRO support for UDP encapsulating protocols')
