vendor_quirks: implement two vendor quirks

Browse Source 
ignore_bss_tm_candidates:
  When a BSS requests a station roam it can optionally include a
  list of BSS's that can be roamed to. IWD uses this list and only
  scans on those frequencies. In some cases though the AP's list
  contains very poor options and it would be better for IWD to
  request a full neighbor report.

replay_counter_mismatch:
  On some Aruba APs there is a mismatch in the replay counters
  between what is seen in scans versus authentications/associations.
  This difference is not allowed in the spec, therefore IWD will
  not connect. This quirk is intended to relax that check.
