xsk: Inherit need_wakeup flag for shared sockets

Browse source

The flag for need_wakeup is not set for xsks with `XDP_SHARED_UMEM`
flag and of different queue ids and/or devices. They should inherit
the flag from the first socket buffer pool since no flags can be
specified once `XDP_SHARED_UMEM` is specified.

Fixes: b5aea28dca ("xsk: Add shared umem support between queue ids")
