[ofw] [patch][al] reg_mad_pool error flow

[Irena Gannon]

Signed-off-by: Irena Gannon (irena at mellanox.co.il<mailto:irena at mellanox.co.il>)

This patch:
1. Adds ref to h_pool in both success and error flows of reg_mad_pool as it is dereferenced in __cleanup_pool_key in both flows as well
2. Prevents trying to remove a pool_item from a list if it was not inserted into it
