md/raid10: fix set but not used variable in sync_request_write() 



Building with W=1 reports the following:

drivers/md/raid10.c: In function ‘sync_request_write’:
drivers/md/raid10.c:2441:21: error: variable ‘d’ set but not used [-Werror=unused-but-set-variable]
 2441 |                 int d;
      |                     ^
cc1: all warnings being treated as errors

Remove the usage of that variable.

Fixes: 752d0464 ("md: clean up accounting for issued sync IO")
