net/hns3: fix queue state after reset

FLR operation will reset the queue enabling state and
the driver needs to restore the state after reset.
If the driver does not restore the state, it will result
in unpredictable behavior with reset when user start or
stop queue by calling the relevant function if.

This patch fix it by add a queue enabling state restore
function to the reset handler.
