Instead of using the hard-coded value of 0x1f, use 'TASK_TAG' macro instead to construct the ucd_req_ptr->header.dword_0
This is in sync with what the Linux UFS driver does, i.e. set the byte0 equal to TASK_TAG (see [1]).
Setting it to a fixed value of 0x1f is wrong as we define TASK_TAG as 0 inside u-boot ufs framework. So, instead we should use the macro value directly.
