Fix INTERFACES command buffer size to allow more data

reply_size instead sizeof(buffer) should be provided to
hostapd_global_ctrl_iface_interfaces() when processing INTERFACES
commands. The previous use of sizeof(buffer) used a significantly
shorter limit (256 vs. 4096 bytes) for the output and this could have
resulted in unnecessary truncation of the output.
