ext4: actually request zeroing of inode table after grow

Browse source 
commit 310a997fd74de778b9a4848a64be9cda9f18764a 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.
