Xiang Xiao d5d134bc79 fs/aio: raise the default AIO_LISTIO_MAX so LTP keeps passing
The new CONFIG_FS_AIO_LISTIO_MAX option defaults to 10 and lio_listio()
now rejects nent > {AIO_LISTIO_MAX} with EINVAL.  The LTP release pinned
by apps/testing/ltp (20230516) submits 256 requests in a single batch from
conformance/interfaces/lio_listio/2-1.c, so ltp_interfaces_lio_listio_2_1
now fails on every configuration that enables CONFIG_TESTING_LTP
(sim:citest, rv-virt:citest, sim:posix_test):

  lio_listio/2-1.c Error at lio_listio() 22: Invalid argument

The EINVAL check itself is required by POSIX, so keep it and raise the
default instead; the limit no longer costs memory because the requests are
linked through the aiocb's own lio_link.

While here, keep _POSIX_AIO_LISTIO_MAX at its POSIX-mandated value of 2
and let AIO_LISTIO_MAX carry the configurable implementation limit.
