api: fill out attribute information if not valid
translators like readdir-ahead selectively retain entry information of
iatt (gfid and type) when rest of the iatt is invalidated (for write
invalidating ia_size, (m)(c)times etc). Fuse-bridge uses this
information and sends only entry information in readdirplus
response. However such option doesn't exist in gfapi. This patch
modifies gfapi to populate the stat by forcing an extra lookup.
Thanks to Shyamsundar Ranganathan <srangana@redhat.com> and Prashanth
Pai <ppai@redhat.com> for tests.
