Increase buffer size to handle long freq_list entries in config

When all common frequency bands (2.4 GHz, 5 GHz, and 6 GHz) are included
in the freq_list configuration, parsing might fail due to the buffer
being too small to accommodate the full list. This results in partial
and incorrect frequency values being read, which might be subsequently
rejected by the kernel as it cannot find a valid channel for the
malformed frequency.

Fix this by increasing the buffer size to a sufficient length in
wpa_config_read().
