station: replace old BSS with 'best_bss' on roam scan

Browse Source 
The logic here assumed any BSS's in the roam scan were identical to
ones in station's bss_list with the same address. Usually this is true
but, for example, if the BSS changed frequency the one in station's
list is invalid.

Instead when a match is found remove the old BSS and re-insert the new
one.
