[Drbd-dev] [PATCH 09/14] dm: add a missing bio initialization to alloc_tio

[Christoph Hellwig]

The bio in the tio embedded into the clone_info structure is never
initialized.  This is harmless as bio_init only zeroes the structure
and assigns the vectors, but add the initialization to prepare for
refactoring the bio cloning logic.
