Ken Sumrall a0822c5577 fuse: fix attributes after open(O_TRUNC)
The attribute cache for a file was not being cleared when a file is opened
with O_TRUNC.

If the filesystem's open operation truncates the file ("atomic_o_trunc"
feature flag is set) then the kernel should invalidate the cached st_mtime
and st_ctime attributes.

Also i_size should be explicitly be set to zero as it is used sometimes
without refreshing the cache.
