net/mlx4_en: Prevent potential integer overflow calculating Hz
The "freq" variable is in terms of MHz and "max_val_cycles" is in terms
of Hz. The fact that "max_val_cycles" is a u64 suggests that support
for high frequency is intended but the "freq_khz * 1000" would overflow
the u32 type if we went above 4GHz. Use unsigned long long type for the
mutliplication to prevent that.
