md/raid1-10: fix casting from randomized structure in raid1_submit_write()
commit b5a99602b74bbfa655be509c615181dd95b0719e upstream.
Following build error triggered while build with clang version 17.0.0
with W=1(this can't be reporduced with gcc 13.1.0):
drivers/md/raid1-10.c:117:25: error: casting from randomized structure
pointer type 'struct block_device *' to 'struct md_rdev *'
117 | struct md_rdev *rdev = (struct md_rdev *)bio->bi_bdev;
| ^
Fix this by casting 'bio->bi_bdev' to 'void *', as it used to be.
