can: xilinx_can: fix RX overflow interrupt not being enabled
commit 83997997252f5d3fc7f04abc24a89600c2b504ab upstream.
RX overflow interrupt (RXOFLW) is disabled even though xcan_interrupt()
processes it. This means that an RX overflow interrupt will only be
processed when another interrupt gets asserted (e.g. for RX/TX).
Fix that by enabling the RXOFLW interrupt.
Fixes: b1201e44f50b ("can: xilinx CAN controller support")
