Commit Message

These tests use bdrv_write_threshold_exceeded() API, which is used only
for test (since pre-previous commit). Better is testing real API, which
is used in block.c as well.

So, let's call bdrv_write_threshold_check_write(), and check is
bs->write_threshold_offset cleared or not (it's cleared iff threshold
triggered).

Also we get rid of BdrvTrackedRequest use here. Note, that paranoiac
bdrv_check_request() calls were added in 8b1170012b1 to protect
BdrvTrackedRequest. Drop them now.
