arm64: mm: fix show_pte KERN_CONT fallout


[ Upstream commit 6ef4fb38 ]

Recent changes made KERN_CONT mandatory for continued lines. In the
absence of KERN_CONT, a newline may be implicit inserted by the core
printk code.

In show_pte, we (erroneously) use printk without KERN_CONT for continued
prints, resulting in output being split across a number of lines, and
not matching the intended output, e.g.

[ff000000000000] *pgd=00000009f511b003
, *pud=00000009f4a80003
, *pmd=0000000000000000

Fix this by using pr_cont() for all the continuations.
