bnxt_en: Add new BNXT_FLTR_INSERTED flag to bnxt_filter_base struct.
Change the unused flag to BNXT_FLTR_INSERTED. To prepare for multiple pathways that an ntuple filter can be deleted, we add this flag. These filter structures can be retreived from the RCU hash table but only the caller that sees that the BNXT_FLTR_INSERTED flag is set can delete the filter structure and clear the flag under spinlock.
