Fix initialization of ap_table_{max_size,expiration_time}

The config says that the default for ap_table_max_size is 255 and the
default for ap_table_expiration_time is 60. But the code doesn't reflect
the default values mentioned in the sample config file.

These variables completely disable the code for Overlapping Legacy BSS
Condition by default when they are not correctly initialized. WFA
certification requires this feature and therefore an AP would have
failed the certification process unless they were initialized manually
using the configuration file.
