xfs: use bios directly to write log buffers
Currently the XFS logging code uses the xfs_buf structure and
associated APIs to write the log buffers to disk. This requires
various special cases in the log code and is generally not very
optimal.
Instead of using a buffer just allocate a kmem_alloc_larger region for
each log buffer, and use a bio and bio_vec array embedded in the iclog
structure to write the buffer to disk. This also allows for using
the bio split and chaining case to deal with the case of a log
buffer wrapping around the end of the log.
