This patch renames fs/aio.c:'struct timeout' to 'struct aio_timeout'.  The
rationale behind this decision is this type is used only inside the
aforementioned aio.c file and being the type name very generic, it is
likely to cause namespace conflicts in the future.

I actually found it while working on an extended schedule_timeout()- like
API used by robust mutexes but usable by anyone.  There I declared a
'struct timeout' and aio.c complained about it.  I could have also renamed
the struct for the schedule_timeout() like API, but being the aio.c one
specific to the file, I thought it might make more sense to rename the
later.
