net: stmmac: Simplify mtl IRQ status checking

Commit 8a7cb245cf28 ("net: stmmac: Do not enable RX FIFO overflow
interrupts") disabled the RX FIFO overflow interrupts. However, it left the
status variable around, but never checks it.

As stmmac_host_mtl_irq_status() returns only 0 now, the code can be
simplified.
