[PATCH v2] net/ice: fix tm configuration cannot be cleared

[Kaiwen Deng]

When the device is stopped, DPDK resets the commit flag so that
we can update the hierarchy configuration. The commit flag is also
used to determine if the hierarchy configuration needs to be cleared.
When DPDK exits, it always stops the device first and also resets
the commit flag result in the hierarchy configuration is not cleared.

This commit changes DPDK to not reset the commit flag when the
device is stopped. And we prevent additional commit when device is
running by only checking the stop flag.

Fixes: f5ec6a3a1987 ("net/ice: fix TM hierarchy commit flag reset")
