[PATCH 3/4] staging: r8188eu: make two functions static

[Michael Straube]

used in rtw_mlme_ext.c. Make them static.

[PATCH 4/4] staging: r8188eu: remove unnecessary return labels.

[Michael Straube]

Remove the RETURN labels in rtw_alloc_etherdev_with_old_priv() and
rtw_alloc_etherdev() and return directly to clean up the code and
improve readability.
