wifi: iwlwifi: mvm: fix iwl_mvm_scan_fits() calculation

Browse Source 
[ Upstream commit d441622808 ]

The calculation should consider also the 6GHz IE's len, fix that.
In addition, in iwl_mvm_sched_scan_start() the scan_fits helper is
called only in case non_psc_incldued is true, but it should be called
regardless, fix that as well.
