Richard Yao 67395be0c2 Fix userland dereference NULL return value bugs ... * `zstream_do_token()` does not handle failures from `libzfs_init()` * `ztest_global_vars_to_zdb_args()` does not handle failures from `calloc()`. * `zfs_snapshot_nvl()` will pass an offset to a NULL pointer as a source to `strlcpy()` if the provided nvlist is `NULL`. We handle these by doing what the existing error handling does for other errors involving these functions. Coverity complained about these. It had complained about several more, but one was fixed by 570ca4441e and another was a false positive. The remaining complaints labelled "dereferece null return vaue" involve fetching things stored in in-kernel data structures via `list_head()/list_next()`, `AVL_PREV()/AVL_NEXT()` and `zfs_btree_find()`. Most of them occur in void functions that have no error handling. They are much harder to analyze than the two fixed in this patch, so they are left for a follow-up patch.
