Subject: [PATCH v1] bufmgr: pass through I/O stats context in
 FlushUnlockedBuffer()

FlushUnlockedBuffer() accepted io_object and io_context arguments, but
ignored them and always called FlushBuffer() with IOOBJECT_RELATION and
IOCONTEXT_NORMAL.

Fix that by passing the caller-provided io_object and io_context through
to FlushBuffer(). While here, make FlushBuffer() use its io_object
parameter when reporting I/O timing, instead of hardcoding
IOOBJECT_RELATION.
