[GIT PULL 10/22] intel_th: msu: Replace open-coded list_{first,last,next}_entry variants

[Alexander Shishkin]

There are a few places in the code where open-coded versions of list entry
accessors list_first_entry()/list_last_entry()/list_next_entry() are used.

Replace those with the standard macros.
