cifs: fix warning when destroy 'cifs_io_request_pool'
There's a issue as follows:
WARNING: CPU: 1 PID: 27826 at mm/slub.c:4698 free_large_kmalloc+0xac/0xe0
RIP: 0010:free_large_kmalloc+0xac/0xe0
Call Trace:

Obviously, 'cifs_io_request_pool' is not created by mempool_create().
So just use mempool_exit() to revert 'cifs_io_request_pool'.
Fixes: edea94a69730 ("cifs: Add mempools for cifs_io_request and cifs_io_subrequest structs")
