bnxt_en: Reserve rings in bnxt_set_channels() if device is down.
The current code does not reserve rings during ethtool -L when the device
is down. The rings will be reserved when the device is later opened.
Change it to reserve rings during ethtool -L when the device is down.
This provides a better guarantee that the device open will be successful
when the rings are reserved ahead of time.
