MdeModulePkg NvmExpressDxe: Avoid crashing 'Mode' during OpenProtocol 

The gBS->OpenProtocol() calls to open EFI_NVM_EXPRESS_PASS_THRU_PROTOCOL
in NvmExpress.c will crash the data in 'Mode' field of
'Private->Passthru'.

The third parameter of gBS->OpenProtocol() is an output parameter that
stores the address where a pointer to the corresponding Protocol
Interface. The current code mistakenly pass '&Private->Passthru' (a
pointer of the EFI_NVM_EXPRESS_PASS_THRU_PROTOCOL) as the third
parameter. This will crash the data in 'Mode' filed.
