ext4: improving calculation of 'fe_{len|start}' in mb_find_extent()
After first execution of mb_find_order_for_block():
'fe_start' is the value of 'block' passed in mb_find_extent().
'fe_len' is the difference between the length of order-chunk and
remainder of the block divided by order-chunk.
And 'next' does not require initialization after above modifications.
