rust-changelog: removed now useless early conditional for NULL_REVISION
Now that the underlying `RevlogEntry` returned for `NULL_REVISION` is
viable, it has become pointless to check NULL_REVISION several times,
even for performance: the check will be far more frequent than the benefit
of bailing earlier in the rare case where the requested revision is
`NULL_REVISION`.
This case is covered explicitly by the first assertion of
`test_data_from_rev_null`.

rust-revlog: fix RevlogEntry.data() for NULL_REVISION
Before this change, the pseudo-entry returned by `Revlog.get_entry` for
`NULL_REVISION` would trigger errors in application code using it.
For example, this fixes a crash spotted with changelog data
while implementing RHGitaly: `Changelog.data_for_rev(-1)` was already
returning the pseudo content as expected, e.g., for `hg log`, but
`Changelog.entry_for_rev(-1).data()` would still crash with
"corrupted revlog, hash check failed for revision -1". There is
an added test for this scenario.
