Explicitly print the VMSA dump at KERN_DEBUG log level, KERN_CONT uses
KERNEL_DEFAULT if the previous log line has a newline, i.e. if there's
nothing to continuing, and as a result the VMSA gets dumped when it
shouldn't.

The KERN_CONT documentation says it defaults back to KERNL_DEFAULT if the
previous log line has a newline. So switch from KERN_CONT to
print_hex_dump_debug().

Jarkko pointed this out in reference to the original patch. See:
https://lore.kernel.org/all/YuPMeWX4uuR1Tz3M@kernel.org/
print_hex_dump(KERN_DEBUG, ...) was pointed out there, but
print_hex_dump_debug() should similar.
