storage/posix: Avoid excessive logging in posix.v3.3.0qa34

When quota or gsyncd is enabled, the marker translator performs setxattr on
files/directories. If the file/directory is deleted before setxattr, posix gets
an error when it does setxattr and logs it. But its not an error for marker and
it handles the case gracefully. Hence, avoid logging for these keys.
