IB/core: Fix unable to change lifespan entry for hw_counters
This patch fixes the case where 'lifespan' entry of the hw_counters
is not writable. Currently write callback is not exposed for for
the hw_counters sysfs operation. Due to this, modifying lifespan
value results into permission denied error in below example.
echo 10 > /sys/class/infiniband/mlx5_0/ports/1/hw_counters/lifespan
-bash: /sys/class/infiniband/mlx5_0/ports/1/hw_counters/lifespan:
Permission denied
This patch adds the hook to modify any attribute which implements
store() operation.
Fixes: b40f4757daa1 ("IB/core: Make device counter infrastructure dynamic")
