[PATCH 07/15] qla2xxx: Move fields from qla_hw_data to qla_qpair

[Himanshu Madhani <himanshu.madhani@cavium.com>]

From: Quinn Tran <quinn.tran@cavium.com>

o Move chip_reset, enable_class_2 fields from qla_hw_data to qla_qpair
  to reduce cache thrash for target MQ.
o Optimizations to reduce unnecessary memory load for good path io.
