[PATCH 5/5] netfilter: xt_TEE: Clean up tests if NULL returned on failure

[simran singhal <singhalsimran0@gmail.com>]

Some functions like kmalloc/kzalloc return NULL on failure. When NULL
represents failure, !x is commonly used.

This was done using Coccinelle:
@@
expression *e;
identifier l1;
@@
e = \(kmalloc\|kzalloc\|kcalloc\|devm_kzalloc\)(...);
...
- e == NULL
+ !e
