wifi-scripts: ensure get_freq returns int (iw-6.9) 

With `iw` version 6.9 frequencies are now being reported as float,
which is incompatible with wpa_supplicant's config option 'frequency'
which expects an integer.

iwinfo phy0 info output:

Error reported from wpa_supplicant
```console
Fri Jun 21 14:07:22 2024 daemon.err wpa_supplicant[2866]: Line 10: invalid number "5320.0"
Fri Jun 21 14:07:22 2024 daemon.err wpa_supplicant[2866]: Line 10: failed to parse frequency '5320.0'.
Fri Jun 21 14:07:22 2024 daemon.err wpa_supplicant[2866]: Line 16: failed to parse network block.
Fri Jun 21 14:07:22 2024 daemon.err wpa_supplicant[2866]: Failed to read or parse configuration '/var/run/wpa_supplicant-phy1-mesh0.conf'.
```

This affects mesh, adhoc, and client-mode WDS.

Until hostapd/wpa_supplicant is updated (or patched) to support float
frequencies, ensure `get_freq` prints out an integer.
