Will Huang c3fb27d117 qcacld-3.0: Make hdd_switch_sap_channel execute once at same time
The sap unsafe channel restart process include two subprocesses: CSA ie
update and channel switch, but CSA ie update request using
mac->sap.SapDfsInfo to save target channel switch parameters, which
would be overwritten by 2nd sap restart at same time. For example:
SAP1 on chan 1 and SAP2 on chan 36, then lte coex mark chan 1 and
chan 36 as unsafe channels, now SAP1 and SAP2 would switch to same
channel, but actually they can be on different channels doing DBS.

To fix it, one option is save the target channel switch parameters to
different session, but looks it may introduce a lot of code change,
because the logic is shared with DFS/concurrency. So the simple option
is making sap unsafe channel restart execute once at same time.
