Use kvfree() to free the pages and vmas, since they are allocated by kvmalloc_array() in a loop.

Fixes: d4ef647510b1 ("io_uring: avoid page allocation warnings") Cc: stable@vger.kernel.org Signed-off-by: Denis Efremov efremov@linux.com --- I checked the v1 d4ef647510b1 discussion and these lines are using kvfree() https://lkml.org/lkml/2019/5/1/254. This was somehow missed in v2.
