qcacmn: Send WMI_ROAM_OFFLOAD_FLAG_SAE_SAME_PMKID flag to FW

Browse Source 
Send new flag WMI_ROAM_OFFLOAD_FLAG_SAE_SAME_PMKID through
11i offload param to indicate fw whether WLAN_SAE_SINGLE_PMK
feature is enable or not.

If flag is set, fw should use single PMKID for SAE roaming
between VSIE AP(s), else fw should complete roaming by
doing full SAE authentication.
