i40e/i40evf: Use usleep_range() instead of udelay()
As per the Documentation/timers/timers-howto.txt it is preferred to use
usleep_range() instead of udelay() if the delay value is > 10us in
non-atomic contexts.
So, replacing all the instances of udelay() with 10 or greater than 10
micro seconds delay in the driver and using usleep_range() instead.
