md/dm-raid: remove max_write_behind setting limit
The comments said 'vaule in kB', while the value actually means the
number of write_behind IOs. And since md-bitmap will automatically
adjust the value to max COUNTER_MAX / 2, there is no need to fail
early.
Also move some macros that is only used md-bitmap.c.
