[PATCH] rt6_probe_deferred: Do not depend on struct ordering

["Michael Büsch" <m@bues.ch>]

[-- Attachment #1: Type: text/plain, Size: 1021 bytes --]

rt6_probe allocates a struct __rt6_probe_work and schedules a work handler rt6_probe_deferred.
But rt6_probe_deferred kfree's the struct work_struct instead of struct __rt6_probe_work.
This works, because struct work_struct is the first element of struct __rt6_probe_work.

Change it to kfree struct __rt6_probe_work to not implicitly depend on
struct work_struct being the first element.

This does not affect the generated code.
