sfc: reduce the number of requested xdp ev queues
Without this change the driver tries to allocate too many queues,
breaching the number of available msi-x interrupts on machines
with many logical cpus and default adapter settings:
Insufficient resources for 12 XDP event queues (24 other channels, max 32)
Which in turn triggers EINVAL on XDP processing:
sfc 0000:86:00.0 ext0: XDP TX failed (-22)
