mei: avoid iterator usage outside of list_for_each_entry

commit c10187b1c5ebb8681ca467ab7b0ded5ea415d258 upstream.

Usage of the iterator outside of the list_for_each_entry
is considered harmful. https://lkml.org/lkml/2022/2/17/1032

Do not reference the loop variable outside of the loop,
by rearranging the orders of execution.
Instead of performing search loop and checking outside the loop
if the end of the list was hit and no matching element was found,
the execution is performed inside the loop upon a successful match
followed by a goto statement to the next step,
therefore no condition has to be performed after the loop has ended.
