  ps2: check PS2Queue wptr pointer in post_load routine

In commit 802cbcb7300, most issues have been fixed when qemu guest
migration. But the queue size still need to check whether is equal to
PS2_QUEUE_SIZE. If yes, the wptr should set as 0. Or, wptr would larger
than PS2_QUEUE_SIZE and never come back when ps2_queue_noirq is called.
This could lead to OOB access, add check to avoid it.
