NTB: Fix typo in setting one translation register
In the code for Xeon devices in back-to-back mode with xeon_errata_workaround disabled, the downstream device puts the wrong value in SNB_B2B_XLAT_OFFSETL (SNB_MBAR01_DSD_ADDR vs. SNB_MBAR01_USD_ADDR). This was spotted while reading code, since the typo has no practical effect, at least for now: the low 32 bits of both constants are actually identical anyway. However, it's clearer and safer to use the right name. Signed-off-by: Roland Dreier <roland@purestorage.com> Signed-off-by: Jon Mason <jon.mason@intel.com>
