[PATCH 02/10] xfs: set lv_bytes in xlog_write_one_vec

[Christoph Hellwig <hch@lst.de>]

lv_bytes is mostly just use by the CIL code, but has crept into the
low-level log writing code to decide on a full or partial iclog
write.  Ensure it is valid even for the special log writes that don't
go through the CIL by initializing it in xlog_write_one_vec.
