If LL_LT_SAP is already present and if STA tries to
come up on same mac, then it may result in data loss
on LL_LT_SAP as STA will need ROC on the connection
channel for some time, to avoid these data loss during
STA connection, add logic to switch the bearer for LL_LT_SAP
data to non-wlan and once connection completes, switch back
the bearer to wlan.
