ext4: fix estimate extent index blocks in ext4_ext_index_trans_blocks()

Browse source

The estimate of the number of impacted extent tree index blocks could be
one-too-low. If we modify say 2 extents, already two leaf index blocks
could be impacted, not just one the current estimate counts with. Fix
the estimate.
