taprio: Use taprio_reset_tc() to reset Traffic Classes configuration
[ Upstream commit 7c16680a08ee1e444a67d232c679ccf5b30fad16 ]
When destroying the current taprio instance, which can happen when the
creation of one fails, we should reset the traffic class configuration
back to the default state.
netdev_reset_tc() is a better way because in addition to setting the
number of traffic classes to zero, it also resets the priority to
traffic classes mapping to the default value.
Fixes: 5a781ccbd19e ("tc: Add support for configuring the taprio scheduler")
