Subject: [PATCH] lib: fix incorrect kernel-doc comment syntax in file

The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
There are certain files in lib and lib/zstd, which follow this syntax,
but the content inside does not comply with kernel-doc.
Such lines were probably not meant for kernel-doc parsing, but are parsed
due to the presence of kernel-doc like comment syntax(i.e, '/**'), which
causes unexpected warnings from kernel-doc.

E.g., presence of kernel-doc like comment in lib/zstd/compress.c at
header causes these warnings by kernel-doc:
"warning: cannot understand function prototype: 'const U32 g_searchStrength = 8;  '"

Similarly for other files too.

Provide a simple fix by replacing such occurrences with general comment
format, i.e. '/*', to prevent kernel-doc from parsing it.
