qcacmn: Fix DFS kernel panic

Forráskód böngészése 
Problem:
During DFS attach the DFS related timers are initialized only if
the DFS is not offloaded.
When user issues a bangradar command for full offload where DFS is
offloaded to FW, HOST is trying to set a un-initialized timer and
leads to a crash.

Solution:
Handle bangradar command in HOST only if the DFS is not offloaded.
