Add frequency to operating class determination for 5 GHz channel 144

Commit 45c3e729527a ("Add frequency to operating class determination
for 5 GHz 100..140") extends ieee80211_freq_to_channel_ext() with
knowledge of the operating classes for the 5 GHz channels 100..140.

Per "Table E-4 - Global operating classes" in IEEE Std 802.11-2020, 5
GHz channel 144 also maps to same operating classes, so update hostapd
code to reflect the change.

This issue is found when OCV enabled and 4-way-handshake failed due
to client OCI includes op_class 0 for channel 144. This showed
up in following manner in the debug log:

WPA: OCI KDE in EAPOL-Key - hexdump(len=9): dd 07 00 0f ac 0d 00 90 00
Error interpreting OCI: unrecognized opclass/channel pair (0/144)
