mkfs.nilfs2: remove unnecessary local variables in prepare_dat()

Browse Source 
Fix the following gcc warnings that appear on recent distros:

mkfs.c: In function 'prepare_dat':
mkfs.c:1534:16: warning: variable 'vblocknr' set but not used
 [-Wunused-but-set-variable=]
 1534 |         int i, vblocknr = 0;
      |                ^~~~~~~~
mkfs.c:1530:33: warning: variable 'entry' set but not used
 [-Wunused-but-set-variable=]
 1530 |         struct nilfs_dat_entry *entry;
      |                                 ^~~~~
