apparmor: Return directly after a failed kzalloc() in two functions 

1. Return directly after a call of the function “kzalloc” failed
   at the beginning in these function implementations.

2. Omit extra initialisations (for a few local variables)
   which became unnecessary with this refactoring.

This issue was detected by using the Coccinelle software.
