drivers: net: xgene: Move status variable declaration into CONFIG_ACPI block

When CONFIG_ACPI is unset (arm allyesconfig), status is unused.

drivers/net/ethernet/apm/xgene/xgene_enet_xgmac.c:383:14: warning:
unused variable 'status' [-Wunused-variable]
acpi_status status;

Move the declaration into the CONFIG_ACPI block so that there are no
compiler warnings.
