iwlwifi: correct frequency settings

Browse Source 
After commit 59eb21a650
"cfg80211: Extend channel to frequency mapping for 802.11j"
we use uninitialized sband->band when assign channel frequencies, what
results that 5GHz channels have erroneous (zero) center_freq value.

Patch fixes problem and simplifies code a bit.
