Wolfram Sang 12765517d9 device_attributes: add sysfs_attr_init() for dynamic attributes
Made necessary by 6992f53349 ("sysfs: Use
one lockdep class per sysfs attribute").

Prevents further "key xxx not in .data" bug-reports.  Although some
attributes could probably be converted to static ones, this is left for
people having hardware to test.

Found by this semantic patch:

@ init @
type T;
identifier A;
@@

        T {
                ...
                struct device_attribute A;
                ...
        };

@ main extends init @
expression E;
statement S;
identifier err;
T *name;
@@

        ... when != sysfs_attr_init(&name->A.attr);
(
+       sysfs_attr_init(&name->A.attr);
        if (device_create_file(E, &name->A))
                S
|
+       sysfs_attr_init(&name->A.attr);
        err = device_create_file(E, &name->A);
)

While reviewing, I put the initialization to apropriate places.
