RDMA/hns: Fix 1bit-ECC recovery address in non-4K OS 

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IAMO4D



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

The 1bit-ECC recovery address read from HW only contain bits 64:12, so
it should be fixed left-shifted 12 bits when used.
