[patch net 1/2] mlxsw: spectrum_dpipe: Fix incorrect entry index

[Jiri Pirko]

From: Arkadi Sharshevsky <arkadis@mellanox.com>

In case of disabled counters the entry index will be incorrect. Fix this
by moving the entry index set before the counter status check.

[Jiri Pirko]

From: Arkadi Sharshevsky <arkadis@mellanox.com>

During rif counter freeing the counter index can be invalid. Add check
of validity before freeing the counter.
