Fail with `custom IP` AP insist to assign 192.168.4.1

[ldab]

I made the following change to show the problem on gateway_common.c and using IDF v4.4.2

The AP insist to stay in the 192.168.4.1 range as indicated on the log below:

I (770) ip select: IP Address:192.168.7.1
I (770) ip select: GW Address:192.168.7.1
I (770) ip select: NM Address:255.255.255.0
I (775) gateway_wifi: IP Address:192.168.4.1
