ext4: improve inode table blocks counting in ext4_num_overhead_clusters
As inode table blocks are contiguous, inode table blocks inside the
block_group can be represented as range [itbl_cluster_start,
itbl_cluster_last]. Then we can simply account inode table cluters and
check cluster overlap with [itbl_cluster_start, itbl_cluster_last]
instead of traverse each block of inode table.
By the way, this patch fixes code style problem of comment for
ext4_num_overhead_clusters.
[ Merged fix-up patch which fixed potentially access to an
uninitialzied stack variable. --TYT ]
