Subject: [PATCH v2 1/9] sh: fault: Fix duplicate printing of "PC:"

Somewhere along the patch handling path, both the old "printk(KERN_ALERT
...)" and the new "pr_alert(...)" were retained, leading to the
duplicate printing of "PC:".

Drop the old one.

Fixes: eaabf98b0932a540 ("sh: fault: modernize printing of kernel messages")
