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')
