md/raid1,raid10: support narrow_write_error when badblocks is disabled

Browse Source 
When badblocks.shift < 0 (badblocks disabled), narrow_write_error()
return false, preventing write error handling. Since narrow_write_error()
only splits IO into smaller sizes and re-submits, it can work with
badblocks disabled.

Adjust to use the logical block size for block_sectors when badblocks is
disabled, allowing narrow_write_error() to function in this case.
