kernel/auditsc.c: use kzalloc instead of kmalloc+memset

In audit_alloc_context() use kzalloc instead of kmalloc+memset.  Also
rename audit_zero_context() to audit_set_context(), to represent it's
inner workings properly.

[akpm@linux-foundation.org: remove audit_set_context() altogether - fold it into its caller]
