[PATCH v1 1/2] ufs: core: add debug log for uic commnad timoeut

[peter.wang at mediatek.com]

From: Peter Wang <peter.wang at mediatek.com>

It is difficult to debug when a UIC command timeout occurs
simultaneously with a UIC command complete interrupt.
Currently, we only see the timeout log without any debug
information, making it unclear whether the UFS device failed
to respond or the host entered an incorrect state.
Add a one-line log to cover this situation.
