fix: block: remove the request_queue argument to the block_bio_remap tracepoint ...

See upstream commit:

  commit 1c02fca620f7273b597591065d366e2cca948d8f
  Author: Christoph Hellwig <hch@lst.de>
  Date:   Thu Dec 3 17:21:38 2020 +0100

    block: remove the request_queue argument to the block_bio_remap tracepoint

    The request_queue can trivially be derived from the bio.
