[PATCH] Fix return code of init_module in drivers_net_arlan.c (2)

From:  Pablo Menichini <pablo@menichini.com.ar>

  	This patch returns correct error codes if init_modules fail.
  Because of this, we can take the printks indicating the error as these
  corrected error codes return miningfull information.
