[PATCH trivial] include/linux/memory_hotplug.h: Clean up code

From: chengang
Date: Thu Jun 09 2016 - 23:53:12 EST


From: Chen Gang <chengang@xxxxxxxxxxxxxxxx>

Use one line instead of two lines for pgdat_resize_init, since one line
is still within 80 columns.

Let the second line function parameter almost align with the first line
parameter.

Use pr_warn instead of printk, so also let the line within 80 columns.
