[PATCH 2/5] dpp: don't allow StartEnrollee while connected

[James Prestwood <prestwoj at gmail.com>]

While connected the driver ends up choosing quite small ROC
durations leading to excessive calls to ROC. This also will
negatively effect any wireless performance for the current
network and possibly lead to missed DPP frames.
