[PATCH] EDD: set sysfs attr owner field

From: Matt Domsch <Matt_Domsch@dell.com>

The patch below from Michael E.  Brown properly sets the owner field of a
sysfs attribute.  Without this patch, it is possible to crash the kernel with
a simultaneous insmod/rmmod while reading files exported by the module.
