MdeModulePkg/PartitionDxe: Fix media probe
The call in ProbeMediaStatus() to the ReadDisk() function of the
EFI_DISK_IO_PROTOCOL interface implemented in DiskIoDxe/DiskIo.c
crashed in DiskIo2ReadWriteDisk() because of the NULL value of
the destination buffer pointer.
Pass the address of a buffer in the stack instead of a NULL
pointer.
In addition to avoiding the crash, that way, the media probe does not
depend anymore on the way the EFI_DISK_IO_PROTOCOL implementation deals
with a NULL value of the destination buffer pointer as the UEFI
specification does not specify the expected behaviour.
