Log Message:
Be sure not to make requests over MAXPHYS when employing bounce buffers.
It was previously possible to round up one sector length if the start block
were not properly aligned.

Resolves PR kern/36716. This may also fix the following reported issues
on port-sgimips:
    http://mail-index.netbsd.org/port-sgimips/2005/09/12/0000.html
    http://mail-index.netbsd.org/port-sgimips/2005/09/14/0000.html

While here, be sure to put back allocated bufs, which previously appear
to have been leaked. Further, remove the dead write bounce code which never
got executed anyway.

No complaints on tech-kern.
