coccinelle: zalloc-simple: drop the kmem_alloc rules

Browse Source 
- kmem_alloc() was removed by commit f078d4ea82
  ("xfs: convert kmem_alloc() to kmalloc()")

- kmem_zalloc() was removed by commit 10634530f7
  ("xfs: convert kmem_zalloc() to kzalloc()")

So drop the kmem_alloc rules.

No functional change.
