qcacld-3.0: Initialize fisa flow entry napi id to other than zero value

Zero initialization of Napi id can cause napi id zero context to flush
flow that are uninitialized. Which may cause a race condition if some
other napi context is using the uninitialized fisa flow entry during the
flow learning phase.
