net/mlx5: DR, Fix 'stack guard page was hit' error in dr_rule

Browse source

[ Upstream commit 94a3ad6c08 ]

This patch reduces the size of hw_ste_arr_optimized array that is
allocated on stack from 640 bytes (5 match STEs + 5 action STES)
to 448 bytes (2 match STEs + 5 action STES).
This fixes the 'stack guard page was hit' issue, while still fitting
majority of the usecases (up to 2 match STEs).
