wifi: iwlwifi: mvm: always apply 6 GHz probe limitations

When scanning on 6 GHz we allocate a set of short-SSIDs and BSSIDs to
probe. However, when we need to do an active scan because of a hidden
SSID, then we could add too many entries for probing causing an
assertion in the firmware input validation.

Reshuffle the code a bit to first calculate the maximum number of
short-SSIDs and BSSIDs that are permitted for the channel. Then ensure
that we do not set more than the permitted number of bits in the
bitmasks and turn on force_passive when we have surpassed the limit.

While at it, also change the logic so that allow_passive is always
disabled in case a hidden SSID is included. Previously, we might not
have done so if we added the short-SSID based on the number of BSSIDs
already in the request.
