Fix <linux/kmsg_dump.h> when CONFIG_PRINTK is not enabled:

include/linux/kmsg_dump.h:56: error: 'EINVAL' undeclared (first use in this function)
include/linux/kmsg_dump.h:61: error: 'EINVAL' undeclared (first use in this function)

Looks like previous commit:
commit 595dd3d8bf953254d8d2f30f99c54fe09c470040

    kmsg_dump: fix build for CONFIG_PRINTK=n

uses EINVAL without having the needed header file(s),
but I'm sure that I build tested that patch also.  oh well.
