qcacld-3.0: Fix race between vdev_stop and update_11k_offload

Currently, host sends 11k offload command to FW as part of RSO Start
and 11k offload disables to FW during RSO Stop. In case of STA+STA
concurrency, Host sends vdev_stop before 11k_deconfig for
currently enabled STA results to assert in FW.

In order to configure 11k for second STA without assertion, Driver
should de-config 11k for currently enabled STA before vdev stop/delete.

Fix is to configure 11k while start roaming and de-configure 11k
while stop roaming irrespective of the reason for roaming STOP.
