Zijun Hu 4c48aed6df driver core: auxiliary bus: Optimize logic of auxiliary_match_id()
auxiliary_match_id() repeatedly calculates variable @match_size in the
for loop, however, the variable is fixed actually, so it is enough to
only calculate the variable once.

Besides, the function should return directly if name of the @auxdev
does not include '.', but it still iterates over the ID table.

Additionally, statement 'dev_name(&auxdev->dev)' is fixed, but may be
evaluated more than 3 times.

Optimize logic of the function by:
- Move the logic calculating the variable out of the for loop
- Return NULL directly if @p == NULL
- Give the statement an dedicated local variable @auxdev_name
