Subject: Fix incorrectly assigned value in ZSTD_errorFrameSizeInfo
X-Git-Tag: v1.4.0^2~27^2~3

Fix incorrectly assigned value in ZSTD_errorFrameSizeInfo

As documented in `zstd.h`, ZSTD_decompressBound returns `ZSTD_CONTENTSIZE_ERROR`
if an error occurs (not `ZSTD_CONTENTSIZE_UNKNOWN`). This is consistent with
the error checking made in ZSTD_decompressBound, particularly line 545.
