[PATCH] net: ethernet: miss media cleanup behavior

[Wentao Liang <liangwentao@iscas.ac.cn>]

In the de21041_media_timer(), line 1081, when media type is locked,
the code jumps to line 1136 to perform cleanup operations. However,
in the de21040_media_timer(), line 991, the same condition leads to
an immediate return without any cleanup.

To address this inconsistency, we have added a jump statement to the
de21040_media_timer() to ensure that cleanup operations are executed
before the function returns.
