RDMA/hns: Support reset recovery for RoCE bonding

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I6Z4E9



---------------------------------------------------------------

Currently, a RoCE bond device cannot be recovered to a bond
device after reset.

Applying this patch, RoCE bonding device 'hns_bond_xx' can be recovered
after reset, including the following changes:
   1. modify the condition for juding whether bond_grp is active, as the
      bond_grp may be also holding HNS_ROCE_CHANGE_BOND during reset init.
      Thus, as long as the bond_grp's state is not
      HNS_ROCE_BOND_NOT_BONDED, it should be considered active.
   2. update the link status of slave in bond_grp from NIC bonding driver
      right before sending command to firmware, as RoCE driver is uninited
      for a while in reset process, and during this period bond_grp cannot
      update the information.
   3. After the reset, re-config the bond_grp information to firmware,
      as the firmware is also reset and the previous configuration is
      cleared.
