[PATCH] arm64: Neaten show_regs, remove KERN_CONT

[Joe Perches <joe@perches.com>]

commit db4b0710fae9 ("arm64: fix show_regs fallout from KERN_CONT changes")
corrected the KERN_CONT fallout from commit 4bcc595ccd80
("printk: reinstate KERN_CONT for printing continuation lines"), but
the code still has unnecessary KERN_CONT uses.  Remove them.

Miscellanea:

o Remove unnecessary trailing blank from the output too.
