xfs: use bios directly to read and write the log recovery buffers

The xfs_buf structure is basically used as a glorified container for
a memory allocation in the log recovery code.  Replace it with a
call to kmem_alloc_large and a simple abstraction to read into or
write from it synchronously using chained bios.
