Subject: [PATCH 04/11] mm/damon/vaddr: Remove an unnecessary warning message

The DAMON virtual address space monitoring primitive prints a warning
message for wrong DAMOS action.  However, it is not essential as the
code returns appropriate failure in the case.  This commit removes the
message to make the log clean.

Fixes: 6dea8add4d28 ("mm/damon/vaddr: support DAMON-based Operation Schemes")
