fanatic: nc_receive might return too slow

[Stefan Bader]

SRU justification:

Impact: When running the test-local-(lxd|docker) tests, the long data test is sending two pieces of data. In some rare cases it was observed that the second send was succeeding while the receive side was not completely closed down after getting the first part. This broke the test sequence and ended in both master/slave being stuck in waiting for data.

Fix: Adding a short delay after each successful send avoids this issue. While being on this, also fixing the direction of the repeat counter (was counting up instead of down).

Testcase: running the dep8 tests for the ubuntu-fan package.

Regression risk: low (and limited to test functionality)
