Give remedial suggestion for hostapd bug

Hostapd v2 introduces a bug which currently throws the following error
and initialization fails
    nl80211: Could not configure driver mode
    nl80211 driver initialization failed.
    hostapd_free_hapd_data: Interface wlp3s0ap wasn't started

Give a suggestive message to the user when hostapd fails because of the
above bug outlining the workaround mentioned in the above bug report.
