staging: axis-fifo: flush RX FIFO on read errors
Flush stale data from the RX FIFO in case of errors, to avoid reading
old data when new packets arrive.
Commit c6e8d85fafa7 ("staging: axis-fifo: Remove hardware resets for
user errors") removed full FIFO resets from the read error paths, which
fixed potential TX data losses, but introduced this RX issue.
