[PATCH 7/7] tests: hwsim: Add test_ap_reload_bss_only

[Raphaël Mélotte]

The test checks that when the SSID of a BSS is changed using
SET+RELOAD_BSS, the stations already connected to other BSSes on the
same radio are not disconnected.

It also checks that stations can connect using the new SSID after the
reload.
