commit 0706a78f31c4217ca144f630063ec9561a21548d upstream.
This reverts commit bd0687c18e635b63233dc87f38058cd728802ab4.
This patch causes a Tx only workload to go to sleep even when it does
not have to, leading to misserable performance in skb mode. It fixed
one rare problem but created a much worse one, so this need to be
reverted while I try to craft a proper solution to the original
problem.
Fixes: bd0687c18e63 ("xsk: Do not sleep in poll() when need_wakeup set")
