[rt2x00-users] [PATCH 14/17] rt2x00: Don't initialize beacon interval to 0 on rt2800 devices

From: Helmut Schaa <helmut.schaa at googlemail.com>

Activating the TBTT interrupt when a beacon interval of 0 is configured
results in an interrupt storm causing the machine to hang. Hence,
initialize the beacon interval to a reasonable default of 100TUs.
