[PATCH] slip.c: current state cleanup

[Felipe W Damasio <felipewd@terra.com.br>]

	Hi Jeff,

	Patch against 2.6-test5.

	Removes current->state = TASK_RUNNING after calling schedule_timeout, 
which already guarantees that the task will be TASK_RUNNING.

	Also (but I'm not about this one) adds a set_current_state with a 
memory barrier before calling schedule_timeout.

	Please review this last bit and applies if it looks good.

	Thanks,

Felipe
