lib: zstd: Revise the warning fix at zstd_reset_cstream()

Subsequent to commit 15f1b5e137 {"lib: zstd: Fix a warning in zstd_reset_cstream()"}

- As referenced by Nick Terrelln ~ the ZSTD maintainer in the
  linux kernel [1], making zstd_reset_cstream() functionally
  identical to ZSTD_resetCStream() would be the perfect way to
  fix the warning without touching any core functions or breaking
  other parts of the code.
