[PATCH] reiserfsprogs: remove dependency on asm/unaligned.h

[Jeff Mahoney <jeffm@suse.com>]

 We probably shouldn't have ever been including asm/unaligned.h, though I
 think I'm the one who might've added it there in the first place.

 This patch borrows the unaligned accessor functions from the 3.6.20 code.
