MdeModulePkg NvmExpressDxe: Fix invalid queue size when creating IO queues
The Maximum Queue Entries Supported (MQES) field in the CAP (Controller
Capabilities) register for a NVMe controller restrict the maximum
individual queue size that the controller supports.
The origin code does not check this value and always uses a hardcode value
when creating I/O submission/completion queues for asynchronous
transmission. The hardcode value might be larger than the MQES field, this
will lead to an 'Invalid Queue Size' error when creating I/O
submission/completion queues.
The patch will add checks to make sure proper queue size is passed when
creating I/O submission/completion queues.
