Subject: drivers: net: xgene: Remove acpi_has_method() calls
Patch-mainline: v5.4-rc1
Git-commit: 570d785ba46b947e0ded0c38955c43d1d7867c12
References: bsc#1154353

acpi_evaluate_object will already return an error if the needed method
does not exist. Remove unnecessary acpi_has_method() calls and check the
returned acpi_status for failure instead.
