net: hsr: hsr_slave: Fix the promiscuous mode in offload mode
commit e748d0fd66ab ("net: hsr: Disable promiscuous mode in offload mode") disables promiscuous mode of slave devices while creating an HSR interface. But while deleting the HSR interface, it does not take care of it. It decreases the promiscuous mode count, which eventually enables promiscuous mode on the slave devices when creating HSR interface again. Fix this by not decrementing the promiscuous mode count while deleting the HSR interface when offload is enabled.
