net: cls_api: Fix uninitialised struct field bo->unlocked_driver_cb

Browse Source 
[ Upstream commit 990b03b05b ]

The 'unlocked_driver_cb' struct field in 'bo' is not being initialized
in tcf_block_offload_init(). The uninitialized 'unlocked_driver_cb'
will be used when calling unlocked_driver_cb(). So initialize 'bo' to
zero to avoid the issue.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 0fdcf78d59 ("net: use flow_indr_dev_setup_offload()")
