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.
