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);
