Suppress Clang Static Analyzer warning about SNPRINTF_BLKPTR()
Clang's static analyzer pointed out that if we can pass a -1 array index to copyname[copies] if there are no valid DVAs. This is an absurd situation, but it suggests that we are missing an assertion, so we add it. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Richard Yao <richard.yao@alumni.stonybrook.edu> Closes #14575
