[PATCH] replace kernel_thread() with kthread_run() in RT2870

[Peter Teoh]

As advised by Greg KH:

http://lkml.org/lkml/2009/3/13/131

Replaced the usage of kernel_thread() with kthread_run().   Compiled
successfully, but not tested as I don't have the hardware.

(parsed by scripts/checkpatch.pl as well).

Thanks.

Replace use of kernel_thread() with kthread_run(), as the former is deprecated.
