Apply to calculateBDSHeight() function the first hunk of commit 243d134 ("Fix some bug for some resolutions") from https://github.com/intel/intel-ipu3-pipecfg.git. The condition for the computed IF rectangle height to be matched against the desired alignment now makes sure that it is included in the minimum and maximum acceptable values.
