qcacld-3.0: Avoid STA CSA during connecting
When process new beacon of current AP during connecting: after pe session
created and before peer assoc, peer phy mode isn't configured, in
lim_process_beacon_eht_op, current channel width is treated as 20M wrongly,
the channel width in eht op of beacon usually larger than 20M, so CSA is
started and RSO is disabled wrongly, although CSA not handled for vdev not
up, RSO can't be enabled any more.
To fix it, only handle eht op of beacon when sta vdev connected.
