Dmitry Antipov be50df31c4 block: bio-integrity: fix kcalloc() arguments order 
When compiling with gcc version 14.0.1 20240116 (experimental)
and W=1, I've noticed the following warning:

block/bio-integrity.c: In function 'bio_integrity_map_user':
block/bio-integrity.c:339:38: warning: 'kcalloc' sizes specified with 'sizeof'
in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
  339 |                 bvec = kcalloc(sizeof(*bvec), nr_vecs, GFP_KERNEL);
      |                                      ^
block/bio-integrity.c:339:38: note: earlier argument should specify number of
elements, later size of each element

Since 'n' and 'size' arguments of 'kcalloc()' are multiplied to
calculate the final size, their actual order doesn't affect the
result and so this is not a bug. But it's still worth to fix it.

Fixes: 492c5d4559 ("block: bio-integrity: directly map user buffers")
