[PATCH] wpa_cli: Fix endless loop relating to STA-NEXT

[greearb at candelatech.com]

From: Ben Greear <greearb at candelatech.com>

Starting 'wpa_cli -g /foo' against a supplicant that did not
have AP mode support compiled in would cause an endless loop of
log messages in the supplicant, and wpa_cli would not actually work
properly.

This fix was inspired by one posted by Denton Gentry:
