Subject: mm/damon/vaddr: remove an unnecessary warning message
X-Git-Tag: iomap-folio-5.17e~41^2~11

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.
