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

Browse Source 
[ Upstream commit ce196f6297 ]

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

Currently, the driver will shift the address left by PAGE_SHIFT when
used, which is wrong in non-4K OS.
