    bcm53xx: use -ENOENT error for TRX parser workaround patch
    
    Change return value from -EINVAL to -ENOENT for the TRX parser
    workaround patch as it's better suited and it's the common exit error
    for parser failing parsing for expected condition (partition not init,
    zero partition found in the schema, magic values not matching)
    
    Also this is needed for a pending upstream patch that will permit parser
    to fail and be skipped for subpartitions only with the -ENOENT error.
