[SCSI] ufs: fix register address in UIC error interrupt handling

In UIC error interrupt handling, it checks if UIC data link layer error
code indicates PA_INIT_ERROR in order to determine whether a fatal error
handling is needed or not.

But the code tries to read UIC data link layer error code from wrong
REG_UIC_ERROR_CODE_PHY_ADAPTER_LAYER, it should be
REG_UIC_ERROR_CODE_DATA_LINK_LAYER.
