qcacld-3.0: Fix memory leak in dfs module

Fix memory leak in dfs module by removing check for the board id.

During dfs_attach dfs_hw_bd_id was zero, so memory was allocated for
pulses_ext_seg but in wma registration process correct board was
updated. In dfs_detach while freeing the memory we check for the
board id and we leaked the memory for pulses_ext_seg.
