[igt-dev] [PATCH i-g-t] tests/kms_atomic_transition: Reduce the number of iterations on modeset-transition

[Mohammed Thasleem]

Due to the more number of iterations, "modeset-transition" tests are
getting timed out on CI. Reducing the number of iterations on pipes
(e.g for 4 pipes it would be 8 iterations). Which can save a lot of
execution time.
Earlier it was 1 << j (nuber of pipes), which is changed to j << 1.

Table for reference:
j  | 1 << j | j << 1
---------------------
0  |    1   |   0
1  |    2   |   2
2  |    4   |   4
3  |    8   |   6
4  |   16   |   8
5  |   32   |   10
