[NTOS:MM] Add debug print to MiAllocateContiguousMemory in out-of-memory case

[binarymaster]

I'm still investigating random out-of-memory problem with patched xboxvmp (video miniport driver for Xbox, see PR #1896), which we discussed with @ThFabba on Mattermost.

We came to the conclusion there is no bug in the memory manager, but for some reason the memory is full at this early loading stage. This pull request adds a debug print for the code path I'm hitting, because there are no other debug prints signaling about outage of memory.

Is it somehow possible to dump the list of all loaded modules and see their paged vs. nonpaged pool usage?

* System info:
  mod [address]        - List all modules or the one containing address.

* Others:
  !poolused [Flags [Tag]] - Display pool usage.
  !filecache           - Display cache usage.

I tried all these commands, but there is nothing suspicious. 🤔
