io_uring: fix missing kmap() declaration on powerpc

Christophe reports that current master fails building on powerpc with
this error:

   CC      fs/io_uring.o
fs/io_uring.c: In function ‘loop_rw_iter’:
fs/io_uring.c:1628:21: error: implicit declaration of function ‘kmap’
[-Werror=implicit-function-declaration]
     iovec.iov_base = kmap(iter->bvec->bv_page)
                      ^
fs/io_uring.c:1628:19: warning: assignment makes pointer from integer
without a cast [-Wint-conversion]
     iovec.iov_base = kmap(iter->bvec->bv_page)
                    ^
fs/io_uring.c:1643:4: error: implicit declaration of function ‘kunmap’
[-Werror=implicit-function-declaration]
     kunmap(iter->bvec->bv_page);
     ^

which is caused by a missing highmem.h include. Fix it by including
it.
