net: ethernet: ti: cpsw: fix extra rx interrupt
[ Upstream commit 51302f77bedab8768b761ed1899c08f89af9e4e2 ]
Now RX interrupt is triggered twice every time, because in
cpsw_rx_interrupt() it is asked first and then disabled. So there will be
pending interrupt always, when RX interrupt is enabled again in NAPI
handler.
Fix it by first disabling IRQ and then do ask.
Fixes: 870915feabdc ("drivers: net: cpsw: remove disable_irq/enable_irq as irq can be masked from cpsw itself")
