Make it possible to schedule image requests on a workqueue. This fixes
parent chain recursion added in the previous commit and lays the ground
for exclusive lock wait/wake improvements.
The "wait for pending subrequests and report first nonzero result" code
is generalized to be used by object request state machine.
