Previously, we clone both bio and repl_bio in raid10_write_request,
then add the cloned bio to plug->pending or conf->pending_bio_list
based on plug or not, and most of the logics are same for the two
conditions.
So introduce handle_clonebio (a better name is welcome) for it, and
use replacement parameter to distinguish the difference. No functional
changes in the patch.

Another reason for it is to improve the readability of code, but
I didn't touch raid10 before so this is labeled as RFC.

Maybe raid10_write_one_disk? Please replace 'i' with a meaningful name and
change to 'boo' for replacement.

Thanks for review, I will use it unless a better name is found.

Ok, I would replace 'i' with 'n_copy', what is the meaning of 'boo'?
IMO, replacement fits better here, thanks.
