net: hns3: Modify hns3_get_max_available_channels

Browse Source 
The current hns3_get_max_available_channels returns the total number
of queues for the device, which makes ethtool -L set the number of queues
per channel queues incorrectly, so hns3_get_max_available_channels should
return the maximum available number of queues per channel, depending on
the total number of queues allocated and the hardware configurations.
