netfilter: nf_tables: fix memory leak in nf_tables_newrule()
[ Upstream commit d077e8119ddbb4fca67540f1a52453631a47f221 ]
In nf_tables_newrule(), if nft_use_inc() fails, the function jumps to
the err_release_rule label without freeing the allocated flow, leading
to a memory leak.
Fix this by adding a new label err_destroy_flow and jumping to it when
nft_use_inc() fails. This ensures that the flow is properly released
in this error case.
