lib: zstd: Fix -Wstringop-overflow warning
Fix the following -Wstringop-overflow warning when building with GCC 11+:
lib/zstd/decompress/huf_decompress.c: In function ‘HUF_readDTableX2_wksp’:
lib/zstd/decompress/huf_decompress.c:700:5: warning: ‘HUF_fillDTableX2.constprop’ accessing 624 bytes in a region of size 52 [-Wstringop-overflow=]

by using pointer notation instead of array notation.
This is one of the last remaining warnings to be fixed before globally
enabling -Wstringop-overflow.
