Subject: [PATCH] zram: zcomp_strm remove ambiguous description

From: wangyong <wang.yong12@....com.cn>

buffer element in the structure is only used for compression.
buffer element is not used in decompression.
So "/* compression/decompression buffer */" is a little ambiguous.

buffer is used in the following two places:
1.__zram_bvec_write: src = zstrm->buffer
2.zcomp_compress: crypto_comp_compress(zstrm->tfm,
                        src, PAGE_SIZE,
                        zstrm->buffer, dst_len);
