> In HDFS-10939, {{unprotectedSetXAttrs}} was optimized to use IIP instead of path string.
> This jira is to do the same on {{unprotectedRemoveXAttrs}}.
> No performance test specifically for this is done yet, but it's not hard to see if a
usage pattern of frequent removexattr could induce perf issues.
