ext4: actually request zeroing of inode table after grow

commit 310a997f upstream.

It is never possible, that number of block groups decreases,
since only online grow is supported.

But after a growing occured, we have to zero inode tables
for just created new block groups.

Fixes: 19c5246d ("ext4: add new online resize interface")
