qcacld-3.0: Invalid offchannel freq sent in tdls offchannel command

In WMI_TDLS_SET_OFFCHAN_MODE_CMDID the offchannel freq is set to invalid
value due to uninitialized local tdls_channel_switch_params type variable
resulting in fw reading incorrect non zero offchanel freq.

Fix, to zero initialize the local tdls_channel_switch_params variable.
