- As referenced by Nick Terrelln ~ the ZSTD maintainer in the linux kernel, making zstd_reset_cstream() functionally identical to ZSTD_resetCStream() would be the perfect way to fix the warning without touching any core functions or breaking other parts of the code.

- The previous patch throws the following warning:
../linux/lib/zstd/zstd_compress_module.c: In function ‘zstd_reset_cstream’:

cc1: all warnings being treated as errors
Since we have a choice to either use ZSTD_CCtx_reset or ZSTD_CCtx_setPledgedSrcSize instead of ZSTD_resetCStream, let's switch to ZSTD_CCtx_setPledgedSrcSize to not have any unnecessary warns alongside the kernel build and CI test build.

- This fixes the below warning:
../lib/zstd/zstd_compress_module.c: In function 'zstd_reset_cstream':
../lib/zstd/zstd_compress_module.c:136:9: warning: 'ZSTD_resetCStream' is deprecated [-Wdeprecated-declarations]
136 | return ZSTD_resetCStream(cstream, pledged_src_size);
| ^~~~~~
In file included from ../include/linux/zstd.h:26,
from ../lib/zstd/zstd_compress_module.c:15:
../include/linux/zstd_lib.h:2277:8: note: declared here
2277 | size_t ZSTD_resetCStream(ZSTD_CStream* zcs, unsigned long long pledgedSrcSize);
| ^~~~~~~~~~~~~~~~~
ZSTD_resetCstream is deprecated and zstd_CCtx_reset is suggested to use hence let's switch to it.
