net/mlx5: fix interrupt installation timing

Currently, the DevX counter query works asynchronously with Devx
interrupt handler return the query result. When port closes, the
interrupt handler will be uninstalled and the Devx comp obj will
also be destroyed. Meanwhile the query is still not cancelled.

In this case, counter query may use the invalid Devx comp which
has been destroyed, and query failure with invalid FD will be
reported.

Adjust the shared interrupt install and uninstall timing to make
the counter asynchronous query stop before interrupt uninstall.
