To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.
To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].
This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.

When we enter freesync, a full update is triggered and the new vtotal
with extra lines is passed to dml in a stream update. The time gained
from extra vblank lines is calculated in microseconds. We allow zstate
entry if the time gained is greater than 5 ms, which is the current
policy. Furthermore, an optimized value for min_dst_y_next_start is
calculated and written to its register. When exiting freesync, another
full update is triggered and default values are restored.
