[PATCH] lib: zstd: Make ZSTD_compressBlock_greedy_extDict static

[YueHaibing]

Fix sparse warnings:

lib/zstd/compress.c:2252:6: warning:
 symbol 'ZSTD_compressBlock_greedy_extDict' was not declared. Should it be 
static?
lib/zstd/compress.c:2982:14: warning:
 symbol 'ZSTD_createCStream_advanced' was not declared. Should it be static?
