net/i40e: fix queue number error in queue region

Browse Source 
when VSI is enabled with smaller number of queues, for example 1 or 6,
it will cause error.

64 is the max number of queues that can be used for RSS, but VSI might
be created with only few queues.

Fixes: 7cbecc2f74 ("net/i40e: support queue region set and flush")
