[Qemu-trivial] [PATCH v3] translate-all.c: Use tb1->phys_hash_next directly in tb_remove |

When tb_remove was first commited at fd6ce8f6, there were three different
calls pass different names to offsetof. In current codebase, the other two
calls are replaced with tb_page_remove. There is no need to have a general
tb_remove. Omit passing the third parameter and using tb1->phys_hash_next
directly.

v3: Rebasing
v2: Address Peter's comment.
- place comment used belong tb_remove above tb_phys_invalidate.
- remove unnecessary bracket.
