x86, mpx: cleanup: do not pass task around when unnecessary
From: Dave Hansen <dave.hansen@linux.intel.com>
The MPX code can largely only work on the current task. You can
not, for instance, enable MPX management in another process or
thread. You can also not handle a fault for another process
or thread.
Despite this, we pass a task_struct around prolifically. This
patch removes all of the task struct passing for code paths
where the code can not deal with another task (which turns out
to be all of them).
This has no functional changes. It's just a cleanup.
