Subject: [PATCH] be2net: protect eqo->affinity_mask from getting freed twice

There are paths in the driver such as an unrecoverable error (UE) detection
followed by a driver unload wherein be_clear() is invoked twice.
Individual data structures are reset so that they are not cleaned/freed
twice. This patch does the same for eqo->affinity_mask. It is freed only
if EQs haven't yet been destroyed. This fixes a possible crash when
affinity_mask is freed twice.
