netfs: Fix io_uring based write-through

Browse Source 
[This was included in v2 of 9b038d004c, but
v1 got pushed instead]

Fix netfs_unbuffered_write_iter_locked() to set the total request length in
the netfs_io_request struct rather than leaving it as zero.

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