NetworkPkg/DxeNetLib: Set *MediaState to EFI_NO_MEDIA if no SNP handle
In NetLibDetectMediaWaitTimeout(), *MediaState is pre-initialized to
EFI_SUCCESS before the SNP handle lookup. When no SNP handle is found,
the function returns EFI_INVALID_PARAMETER but leaves *MediaState as
EFI_SUCCESS. Callers such as PxeCheckMediaState() that rely solely on
*MediaState (ignoring the return value) incorrectly treat a system with
no network device as having media connected.
Fix this by setting *MediaState = EFI_NO_MEDIA inside the
(SnpHandle == NULL) branch before returning EFI_INVALID_PARAMETER.
Update the @retval comment to document this behavior.
