Update AKMP and proto for driver-based SME while roaming

Browse source 
After roaming to a new AP using driver-based SME and roaming trigger,
AKMP and proto were not updated in wpa_sm. Hence, update AKMP and proto
used with roamed AP when association event received from the driver in
SME offloaded to the driver scenario to avoid incorrect AKMP details in
wpa_supplicant similarly to how the cipher suite updates were added in
commit 2b3e64a0fb ("Update ciphers to address GTK renewal failures
while roaming") .
