netfilter: nf_tables: NULL pointer dereference in nf_tables_updobj()

Browse source

[ Upstream commit dac7f50a45 ]

static analyzer detect null pointer dereference case for 'type'
function __nft_obj_type_get() can return NULL value which require to handle
if type is NULL pointer return -ENOENT.

This is a theoretical issue, since an existing object has a type, but
better add this failsafe check.
