Ovidiu Panait 226082eb17 staging: axis-fifo: flush RX FIFO on read errors 
commit 82a051e255 upstream.

Flush stale data from the RX FIFO in case of errors, to avoid reading
old data when new packets arrive.

Commit c6e8d85faf ("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.
