tsnep: Fix XDP_RING_NEED_WAKEUP for empty fill ring

Browse source

[ Upstream commit 9a91c05f4b ]

The fill ring of the XDP socket may contain not enough buffers to
completey fill the RX queue during socket creation. In this case the
flag XDP_RING_NEED_WAKEUP is not set as this flag is only set if the RX
queue is not completely filled during polling.

Set XDP_RING_NEED_WAKEUP flag also if RX queue is not completely filled
during XDP socket creation.
