SDO client timeout not working as expected when using COCSdoRequestDownload(...)

[MathiasVanbelle]

Describe the bug

SDO-timout of SDDO download request are not always good.

To Reproduce
Steps to reproduce the behavior:

1. try to send every 1ms a SDO request as client
2. use a timeout of 10ms
3. disabling device that should answer
4. timeout should be 10ms, but it is not!

Expected behavior
after disabling device the timeout should be 10ms.

Additional context
Removing the timer in COCSdoTransferFinalize() function seems to fix the problem.
Timing seems ok then.
