lio_listio() never validated 'nent' against {AIO_LISTIO_MAX}, so a
batch larger than the documented limit was silently accepted, and the
hard-coded _POSIX_AIO_LISTIO_MAX value of 2 was too small for real
workloads (LTP uses 10 entries per call).
Add the FS_AIO_LISTIO_MAX Kconfig option (default 10), use it for
_POSIX_AIO_LISTIO_MAX in include/limits.h, validate 'nent' in
lio_listio(), and report the limit through sysconf(_SC_AIO_LISTIO_MAX).
