[libcamera-devel] [PATCH] test: delayed_controls: Remove sequenceOffset

[Jacopo Mondi]

Commit 6f539a6d2fa9 ("delayed_controls: Remove reduandant firstSequence_")
removed support for frame number start offset from the DelayedControls
class, as it is now guaranteed that the first sequence number as it comes
from the V4L2VideoDevice will always be 0.

However the delayed_controls.cpp unit still has two tests that passes
a non-zero first sequence number to the DelayedControl class, causing
the test to spin forever and consequentially fail.

Remove the two tests from the unit to fix this.

The first removed test was testing the class against frame start
sequence numbers greater than zero and can safely be removed.

The second test was instead validating the class against sequence number
overflow, which is now not possible to test anymore as the DelayedControls
class now assumes 0 as first frame sequence number.
