qcacmn: Fix off_channel_bw in tdls_get_wmi_offchannel_bw()
The function tdls_get_wmi_offchannel_bw, returns the off channel
bandwidth value. For BW80 and BWALL types, there is no break.
This could result in the off_chan_bw value overwritten to
WMI_TDLS_OFFCHAN_20MHZ for BW80 and BWALL.
Fix the missing break statement in function
tdls_get_wmi_offchannel_bw to return proper values for
off_chan_bw.
