MdeModulePkg/NonDiscoverablePciDevice: Remove the redundant check
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1422
if (Attributes) {
if ((Attributes & (~(DEV_SUPPORTED_ATTRIBUTES))) != 0) {
return EFI_UNSUPPORTED;
}
}
In above code block,
"If ((Attributes & (~(DEV_SUPPORTED_ATTRIBUTES))) != 0)" is TRUE,
the Attributes must be not 0. So we can remove the redundant
check "if (Attributes)".
