Jon Hunter 7125981c99 nvidia-oot: vblk: Fix build errors for various Linux versions ...

Building the Tegra VBLK driver fails on various Linux v5.x versions due
to mismatches in arguments. Reviewing the Linux history the arguments to
the following functions changed in the following Linux versions ...

1. Linux v5.15
- The function __alloc_disk_node() is updated to pass an additional
  argument of type 'struct request_queue'.

2. Linux v5.16
- The functions blk_get_request() and blk_put_request() are replaced by
  blk_mq_alloc_request() and blk_mq_free_request(), respectively.

3. Linux v5.17
- Removes the argument of type 'struct gendisk' from the function
  blk_execute_rq().

4. Linux v5.18
- Removes the header 'linux/genhd.h'.

5. Linux v6.0
- Replaces the function __alloc_disk_node() with
  blk_mq_alloc_disk_for_queue().

Update the Tegra VBLK driver to ensure that the correct functions and
header files are used per the exact Linux version.
