[dpdk-dev] [PATCH 2/3] net/sfc: revise FW RSRC free error logs in transfer rules

[Ivan Malov]

The current code simply forwards FW resource free failure
to the application leaving the operation incomplete. This
stalls the application and makes debugging very difficult.

Make the driver proceed with handling FW resource free in
the case of errors. Add explicit error logging statements.
