usb: dwc3: Don't use %pK through printk
This is a revert of
commit 04fb365c453e ("usb: dwc3: replace %p with %pK")
When the formatting was changed from %p to %pK that was a security
improvement, as %p would leak raw pointer values to the kernel log.
Since commit ad67b74d2469 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
On the other hand, restricted pointers ("%pK") were never meant to be used
through printk(). They can unintentionally still leak raw pointers or
acquire sleeping looks in atomic contexts.
Switch back to regular %p again.
