[9610] wlbt : Initialization of Newly Introduced cfg80211_roam_info structure from...

From Kernel 4.12.0, a new structure named cfg80211_roam_info
has been introduced in CFG.
cfg80211_roam_info structure is passed in cfg80211_roamed()
API call from Driver.

But, While initializing this structure in SLSI Wifi Driver,
sta_bss info should not be populated, because the new roamed
sta_bss info is retrieved later via cfg80211_get_bss() API
call from sme.
