qcacld-3.0: Refactor sta mode type stop adapter logic

Move the stop adapter logic of below OPMODEs to unified
function. The function is called on adapter level and internally
all the active links are cleaned up.
1) QDF_STA_MODE
2) QDF_P2P_CLIENT_MODE
3) QDF_NDI_MODE
4) QDF_P2P_DEVICE_MODE
5) QDF_NAN_DISC_MODE
