Subject: [PATCH v1 1/2] scsi: ufs: differentiate dev_cmd trace message

From: Bean Huo <beanhuo@...ron.com>

fshcd_exec_dev_cmd() can send query request and NOP request, and it is
confusing that ufshcd_add_query_upiu_trace() prints us the "query_send"
string in the trace log. Change it and add NOP key message in the trace
print according to the dev_cmd type.
