net/mlx5: DR, Fix 'stack frame size exceeds limit' error in dr_rule

If the kernel configuration asks the compiler to check frame limit of 1K,
dr_rule_create_rule_nic exceed this limit:
    "stack frame size (1184) exceeds limit (1024)"

Fixing this issue by checking configured frame limit and using the
optimization STE array only for cases with the usual 2K (or larger)
stack size warning.
