*Refine the coding style according edk2 community's feedback.
Current SNP UNDI Initialize command does not follow the UEFI Spec
to update the SNP MediaPresent field. The result for the Initialize
command execution check should be:
StatFlags: (1) Monitor the upper two bits (14 & 15) in the field to know
whether the command has been executed by the UNDI (Not started, Queued,
Error, Complete). (2) Check the other field to see if there is an active
connection to this network device (used to update MediaPresent).
StatCode: After command execution completes, either successfully or not,
this field contains the result of the command execution (success or failure).
This patch is used to fix it.
NOTE: If any UNDI driver does not follow the UEFI Spec for the media status
update, it may meet failure with this more conditions check (StatFlags).

Some UNDI drivers may not support the cable detect in UNDI INITIALIZE command,
but support the media present check in UNDI GET_STATUS command. Current SNP
driver will set the MediaPresentSupported field to FALSE in EFI_SIMPLE_NETWORK_MODE
for such case, which forbid the media detect from the callers.
This patch updates the SNP driver to support such kind of UNDIs for media detect.
MediaPresentSupported will be set to TRUE, and a GET_STATUS command will be issued
immediately after INITIALIZE command in SNP->Initialize() function, to refresh
the value of MediaPresent in SNP mode data.
