Subject: DPP2: Fix ppkey parsing
X-Git-Tag: hostap_2_10~790

DPP2: Fix ppkey parsing

DPP_CONFIGURATOR_ADD processing of the new ppkey parameter had a
copy-paste error in determining the correct length of this parameter.
Fix that by referencing the correct pointer.

Fixes: 9c1fbff07404 ("DPP2: Generate a privacy protection key for Configurator")
