test/nvmf: Extend ANA state change timeout to 20 seconds

Browse Source 
If a connection is lost, Linux NVMe host tries reconnecting after
10 seconds delay by default. To cover this case, extend the timeout
to 20 seconds. Usually Linux NVMe host recognizes the new ANA state
within 2 seconds.

This patch is for the github issue #2081
