MFC r343696:
net80211: do not setup roaming parameters for unsupported modes.
ifconfig(8) prints per-mode parameters if they are non-zero; since
we have 13 possible modes with 3...5 typically supported this change
should greatly reduce amount of information for 'ifconfig <wlan> list roam'
command.
While here ensure that sta_roam_check() will not use roaming parameters
for unsupported modes (it should not).
This change effectively reverts r188776.
