When sending an adminq command, we wait for the command to complete in a loop. This loop waits for an entire millisecond, when in practice the adminq command is processed often much faster. Change the loop to use i40e_usec_delay instead, and wait for 50 usecs each time instead. This appears to be about the minimum time required, based on some manual observation and testing. The primary benefit of this change is reducing latency of various operations in the PF driver, especially when related to having a large number of VFs enabled.
