Docs/admin-guide/mm/damon/usage: fix wrong usage example of init_regions file

DAMON debugfs interface assumes the users will write all inputs at once. 
However, redirecting a string of multiple lines sometimes end up writing
line by line.  Therefore, the example usage of 'init_regions' file, which
writes input as a string of multiple lines can fail.  Fix it to use a
single line string instead.  Also update the description of the usage to
not assume users will write inputs in multiple lines.
