i40iw: Correct Q1/XF object count equation

[ Upstream commit fe99afd1febd74e0ef1fed7e3283f09effe1f4f0 ]

Lower Inbound RDMA Read Queue (Q1) object count by a factor of 2
as it is incorrectly doubled. Also, round up Q1 and Transmit FIFO (XF)
object count to power of 2 to satisfy hardware requirement.
