Mike Snitzer 666eed4676 dm: fix __send_duplicate_bios() to always allow for splitting IO 
Commit 7dd76d1fee ("dm: improve bio splitting and associated IO
accounting") only called setup_split_accounting() from
__send_duplicate_bios() if a single bio were being issued. But the case
where duplicate bios are issued must call it too.

Otherwise the bio won't be split and resubmitted (via recursion through
block core back to DM) to submit the later portions of a bio (which may
map to an entirely different target).

For example, when discarding an entire DM striped device with the
following DM table:
 vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048
 vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048

Before (broken, discards the first striped target's devices twice):
 device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872
 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872
 device-mapper: striped: target_stripe=0, bdev=7:0, start=2049 len=22528
 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=22528

After (works as expected):
 device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872
 device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872
 device-mapper: striped: target_stripe=0, bdev=7:2, start=2048 len=22528
 device-mapper: striped: target_stripe=1, bdev=7:3, start=2048 len=22528
