This is extremely brittle and potentially dangerous -- it's quite generic so it could swallow the later checks.

It looks like formatting was broken by mistake.
Easy fix by running go fmt ./... from project root

This PR addresses PBM-843 by improving error handling when attempting
physical backups on MongoDB instances running with the inMemory storage engine.
If the
$backupCursorstage is not supported, PBM now returns aclear and user-friendly message:
"physical backup is not supported for the inMemory storage engine"
All existing tests pass locally using Docker and go test.
