libbpf: Don't use kernel-side u32 type in xsk.c
[ Upstream commit a566e35f1e8b4b3be1e96a804d1cca38b578167c ]
u32 is a kernel-side typedef. User-space library is supposed to use __u32.
This breaks Github's projection of libbpf. Do u32 -> __u32 fix.
Fixes: 94ff9ebb49a5 ("libbpf: Fix compatibility for kernels without need_wakeup")
