After commit 5a6c35f9af41 ("block: remove direct_make_request"),
'md' is never used and gcc report build warning:

drivers/md/dm.c:1296:24: warning: unused variable 'md' [-Wunused-variable]
 1296 |  struct mapped_device *md = io->md;
      |                        ^~

Removing it to avoid build warning.
