[PATCH 15/15] aoe: fix sysfs_create_file warnings

[Greg KH <greg@kroah.com>]

From: Greg Kroah-Hartman <gregkh@suse.de>

Moved the attributes into a group, making the compiler be quiet about
ignoring the return value of the file create calls.  This also also
fixed a bug when removing the files, which were not symlinks.
