### Description of PR
In StripedReader#initZeroStrip(), zeroStripeIndices is initialized by
scanning all internal blocks, including parity blocks.
The loop should only scan data block indices, which would make the
implementation match the meaning and allocated size of zeroStripeIndices, and
avoid suggesting that parity block indices may be populated as zero stripe
indices.
### How was this patch tested?
Existing reconstruction tests already cover partial block groups where zero
data strips are padded for decoding. The proposed change should not affect
observable behavior, since parity indices are never valid zero stripe indices
for non-empty block groups.
