Jouni Malinen 3d5b356ac0 tests: Wait for all 4-way handshake pairs in test_ibss_rsn
The handshake between STA2 and STA1 was not tracked previously. For
completeness, include that in the list of handshakes that are explicitly
waited for to complete prior to starting the connectivity tests. Since
all key setup should be done at this point, remove the extra wait before
the last connectivity test between STA1 and STA2.
