resize2fs fails with a high inode density.

Issue

• resize2fs fails with a high inode density.
  For example, the reproducer is below.

  1. Prepare 250 GB PV.
  2. Create VG and 70GB LV
  3. Create a filesystem into the 70GB's LV.
  4. Extend the LV to 220GB.
  5. Run resize2fs to the volume and the command will fail.
  
  The procedure with commands is below.
  
  # pvcreate /dev/vdb
  # vgcreate vg_test
  # lvcreate -n lv_test --size 70G vg_test
  # mkfs.ext4 -b 1024 -g 8192 -N 73400320 -j -v -O large_file -E stride=9494 -t ext4 /dev/mapper/vg_test-lv_test 73400320
  # lvextend --size +150G /dev/mapper/vg_test-lv_test
  # resize2fs /dev/mapper/vg_test-lv_test
  

  The sample error output is below

  # resize2fs /dev/mapper/test-lv_test 
  resize2fs 1.43.4 (31-Jan-2017)

  Please run 'e2fsck -fy /dev/mapper/vg_test-lv_test' to fix the filesystem
  after the aborted resize operation.
