PATCH 1/1 usbip: change dev_attr_group to constant

From: Márton Németh <[email protected]>

The dev_attr_group variable is never changed and it is only passed
to the second parameter of sysfs_create_group() and sysfs_remove_group() functions. These functions are defined in linux/sysfs.h: the second parameter is a pointer to const in both cases.
