docs: sysctl/fs: merge the aio sections 



There are two sections documenting aio-nr and aio-max-nr, merge them.
I kept the second explanation of aio-nr, which seems clearer to me,
along with the effects of the values from the first section.

aio-nr & aio-max-nr

-------------------



aio-nr is the running total of the number of events specified on the

io_setup system call for all currently active aio contexts.  If aio-nr

reaches aio-max-nr then io_setup will fail with EAGAIN.  Note that

raising aio-max-nr does not result in the pre-allocation or re-sizing

of any kernel data structures.

aio-nr shows the current system-wide number of asynchronous io

requests.  aio-max-nr allows you to change the maximum value

aio-nr can grow to.  If aio-nr reaches aio-nr-max then io_setup will

fail with EAGAIN.  Note that raising aio-max-nr does not result in the

pre-allocation or re-sizing of any kernel data structures.
