qcacld-3.0: fix timeout issue when unloading driver with ftm mode

When driver working with FTM mode for qca6174, unloading driver
need send WMI_PDEV_SUSPEND_CMDID to firmware, as firmware has no
code to handle this command for FTM mode, driver will do self recovery
after waiting response timedout. Fix the issue to skip pdev suspend
command with FTM mode for specific target.
