ext4: treat stripe in block unit

Browse source

Stripe is misused in block unit and in cluster unit in different code
paths. User awared of stripe maybe not awared of bigalloc feature, so
treat stripe only in block unit to fix this.
Besides, it's hard to get stripe aligned blocks (start and length are both
aligned with stripe) if stripe is not aligned with cluster, just disable
stripe and alert user in this case to simpfy the code and avoid
unnecessary work to get stripe aligned blocks which likely to be failed.
