[PATCH v1] mm: zswap: Delete comments for "value" member of 'struct zswap_entry'.

[Kanchana P Sridhar]

Made a minor edit in the comments for 'struct zswap_entry' to delete
the description of the 'value' member that was deleted in commit
20a5532ffa53d6ecf41ded920a7b0ff9c65a7dcf ("mm: remove code to handle
same filled pages").

Is it worth adding a Fixes tag for this? FWIW, it's really just a
documentation correction, not an actual bug fix. But it's a "fix"
nevertheless...

FYI, usually the first 12 characters of the SHA1 are enough when
referring to a commit according to [1].
