NotPrimaryError handling fix

[v1k1nghawk]

Setup:
Improperly configured replica set on a server side (server's rs.status() output is "MongoServerError: Our replica set config is invalid or we are not a member of it", client will get NotPrimaryError).
MongoDB - 5.0.9
Mongosh - 1.5.0
Server OS, Client OS - Ubuntu 20.04.4 LTS (GNU/Linux 5.15.0-1020-aws x86_64)

Client's command:

./tpcc.py --config mconfig --warehouses 1000 --clients=100 --no-load --debug mongodb

Crash's output:

"Traceback (most recent call last): File "./tpcc.py", line 244, in driver.loadConfig(config) File "/home/ubuntu/TPCC_1/py-tpcc/pytpcc/drivers/mongodbdriver.py", line 346, in loadConfig exc.code, exc.details, display_uri) UnboundLocalError: local variable 'exc' referenced before assignment"

Proper variable introduced

Subsequent errors have been fixed:

ZeroDivisionError, raised by total_retries/0, handled
