Bogus error when attempting to set property on read-only pool
When attempting to set a property on a read-only pool the zfs command exits with "internal error: out of memory". This happens because in the case of a read-only pool the error list is not filled, which causes the call to nvlist_unpack() in zcmd_read_dst_nvlist() to fail with "ENOTSUP". The code wrongly assumes that the only way nvlist_unpack() can fail is with ENOMEM and calls no_memory() which prints the bogus error and exits.
