edsp: try to read responses even if writing failed
If a solver/planner exits before apt is done writing we will generate
write errors. Solvers like 'dump' can be pretty quick in failing but
produce a valid EDSP error report apt should read, parse and display
instead of just discarding even through we had write errors.
