MFC revision 1.181
When breaking up a large request into smaller ones for the strategy
routine, create all the child bio objects before starting the
requests, rather than starting them as created. This closes a race
whereby some number of child operations could complete before the
rest were ever created, and prematurely freeing the parent bio.
This fixes the panics installing in VMWare and qemu
