Xu Kuohai ee4908f909 bpf: Fix error usage of map_fd and fdget() in generic_map_update_batch() ...

commit fda7a38714 upstream.

1. The ufd in generic_map_update_batch() should be read from batch.map_fd;
2. A call to fdget() should be followed by a symmetric call to fdput().

Fixes: aa2e93b8e5 ("bpf: Add generic support for update and delete batch ops")
