lib/decompress: check for reserved bit corruption in zstd
The patch adds a validation to ensure that the last field, which is
reserved, must be all-zeroes in ZSTD_decodeSeqHeaders. This prevents
potential corruption from going undetected.

Fixes an issue where corrupted input could lead to undefined behavior
due to improper validation of reserved bits.
