gdata: Fix a bug in fetching of the first chunk
gdata: Fix a bug in fetching of the first chunk

kMaxDocumentsPerFirstFeed should have been nuked as part of crrev.com/131038,
but it wasn't. As a result, we were still fetching the first chunk for 200
documents rather than 1000 documents. This is no longer necessary and is now
harmful.

BUG=chromium-os:28381
TEST=files on gdata are shown as before
