Change the error handling for invalid property values
ZFS recv should return a useful error message when an invalid index property value is provided in the send stream properties nvlist With a compression= property outside of the understood range: Before: ``` receiving full stream of zof/zstd_send@send2 into testpool/recv@send2 internal error: Invalid argument Aborted (core dumped) ``` Note: the recv completes successfully, the abort() is likely just to make it easier to track the unexpected error code. After: ``` receiving full stream of zof/zstd_send@send2 into testpool/recv@send2 cannot receive compression property on testpool/recv: invalid property value received 28.9M stream in 1 seconds (28.9M/sec) ``` Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Allan Jude <allan@klarasystems.com> Closes #10631
