[PATCH v2] Staging: dream: pmem: fix some code style issues

[Chihau Chau <chihau@gmail.com>]

From: Chihau Chau <chihau@gmail.com>

This fixes some code style issues like some braces {} deleted becouse
are not necessary for a single statement blocks and to include KERN_
facility level in the printk() functions.
