[PATCH] hostapd: fix BSS parameters change count on link removal

[Johannes Berg]

From: Johannes Berg <johannes.berg at intel.com>

The value currently is simply incremented, but it must not
reach 255 and rather wrap around from 254 to 0, since in
the Reduced Neighbor Report 255 means unknown. Fix that.

Fixes: d95838b7932b ("AP: Add support for testing ML link removal")
