wifi: wilc1000: fix for absent RSN capabilities WFA testcase

Browse Source 
[ Upstream commit 9ce4bb09123e9754996e358bd808d39f5d112899 ]

Mandatory WFA testcase
CT_Security_WPA2Personal_STA_RSNEBoundsVerification-AbsentRSNCap,
performs bounds verfication on Beacon and/or Probe response frames. It
failed and observed the reason to be absence of cipher suite and AKM
suite in RSN information. To fix this, enable the RSN flag before extracting RSN
capabilities.
