Handle announce timeout value that is received as a part of
the TWT setup command and provides it to the firmware through
the WMI_TWT_ADD_DIALOG_CMDID. If timeout value is non-zero
then firmware waits up to timeout value to use data frame as
announcement frame. If timeout value is 0 then firmware sends
explicit QoS NULL frame as announcement frame on SP start.
