bpf: Fix error usage of map_fd and fdget() in generic_map_update_batch()
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: aa2e93b8e58e ("bpf: Add generic support for update and delete batch ops")
