Subject: xtables: Fix for wrong assert() in __nft_table_flush()
X-Git-Tag: v1.8.1~39

xtables: Fix for wrong assert() in __nft_table_flush()

The code obviously tries to assert that nft_table_builtin_find()
returned a valid pointer before dereferencing it, but the wrong argument
was given. Assume this is just a typo and insert the missing underscore.
