Subject: [PATCHv2 06/32] avr32: copy_thread(): rename 'arg' argument to 'kthread_arg'

The 'arg' argument to copy_thread() is only ever used when forking a new
kernel thread. Hence, rename it to 'kthread_arg' for clarity.

Dear Hans-Christian Egtvedt,

Thanks for your feedback! I have removed the unneeded comments.
