net: stmmac: fix return value of __setup handler
commit e01b042e580f1fbf4fd8da467442451da00c7a90 upstream.
__setup() handlers should return 1 on success, i.e., the parameter
has been handled. A return of 0 causes the "option=value" string to be
added to init's environment strings, polluting it.
Fixes: 47dd7a540b8a ("net: add support for STMicroelectronics Ethernet controllers.")
Fixes: f3240e2811f0 ("stmmac: remove warning when compile as built-in (V2)")
