MdeModulePkg/NvmExpressDxe: Fix data buffer not mapped for Write cmd

Within function NvmExpressPassThru():

The data buffer for the below 2 Admin command:
Create I/O Completion Queue command (Opcode 01h)
Create I/O Submission Queue command (Opcode 05h)

are not mapped to the PCI controller specific addresses.

But the current code logic also prevents the below NVM command:
Write (Opcode 01h)

from mapping its data buffer.

Hence, this commit refine the logic to resolve this issue.
