From: Kees Cook <keescook@xxxxxxxxxxxx>
Subject: scripts: kernel-doc: Ignore __alloc_size() attribute

Fixes "Compiler Attributes: add __alloc_size() for better bounds checking"
so that the __alloc_size() macro is ignored for function prototypes when
generating kerndoc. Avoids warnings like:

./include/linux/slab.h:662: warning: Function parameter or member '1' not described in '__alloc_size'
./include/linux/slab.h:662: warning: Function parameter or member '2' not described in '__alloc_size'
./include/linux/slab.h:662: warning: expecting prototype for kcalloc().  Prototype was for __alloc_size() instead
