[PATCH V2] brcmfmac: update beacon IE after bss up and clear when AP stopped

[Wright Feng <wefe@cypress.com>]

Firmware doesn't update beacon/Probe Response vendor IEs correctly when
bss is down, so we move brcmf_config_ap_mgmt_ie after BSS up. And host
driver should clear IEs when AP stopped so that the IEs in host side will
be synced with in firmware side.
