Description:
lcs: Unpredictable results after cable pull/plug-in.

Symptom:
Device not operational anymore after cable pull/plug-in. Unpredictable results
occured, e.g. kernel panic using cards of type QD8F.

Problem:
Stoplan command and delete multicast address command were not proper recognized
by OSA card under heavy network workload.
Channel/device error checks missing in interrupt handler.

Solution:
Missing error checks in interrupt handler added. LCS device recovery improved.
Schedule recovery on card's problems or cable plug-in.
