firmware: xilinx: Propagate actual error from feature check

Browse Source 
When do_fw_call() fails in __do_feature_check_call(), propagate the
actual errno from zynqmp_pm_ret_code() instead of always returning
-EOPNOTSUPP. This gives callers more precise error information. Existing
callers only test ret < 0 and are unchanged by this.
