netfs: Fix writethrough to use collection offload

Browse Source 
Fix writethrough write to set NETFS_RREQ_OFFLOAD_COLLECTION on the request
so that collection is processed asynchronously rather than only right at
the end - and also so that asynchronous O_SYNC writes get collected at all.

Fixes: 288ace2f57 ("netfs: New writeback implementation")
