hostapd: set validity interval for BSS TMRA

This sets the validity interval for the BSS transition candidate
list to the same value as the disassociation timer.

Currently the value is always 0, which is the specification states is a
reserved value. Also, wpa_supplicant and from the looks of it some
Android implementations will outright ignore the candidate list in this
case.
