In C++ bulk_write method return real error code instead of -EIO
Changed bulk_write error report logic

Only return wait error (usually -ETIMEOUT/-110) if wait internal
status (assigned in write completion handler) was set to something
except -ENXIO.

-ENXIO is set by default and means no transactions were sent

v2.20.6.8
Fixed deadlock in callback.cpp

boost::condition_variable::notify* functions should be called when mutex
assotiated with conditiona variable is locked. In other case there is a
possibility of deadlock in pthread internals. In boost 1.47 problem was
solved by adding internal mutex, but there is no fixes in 1.40.

So, to solve deadlocks mutex lock is moved upper and now it's holded
during whoole callback::handler() body.
