sfc: Turn pause frame generation on and off at the MAC, not the RX FIFO
Pause frame generation is gated by both RX_XOFF_MAC_EN and an enable
bit in each MAC. RX_XOFF_MAC_EN bit always reads back as 0 so we need
to set it correctly every time we modify RX_CFG_REG. Simplify this by
always setting it to 1 and only changing the enable bits in the MACs.
