[PATCH 1/1] md/bitmap.c:bitmap_status(): Fix filename escaping

[Nominal Animal]

The call to seq_file_path() does not include backslash itself
in the set of file names escaped. This results in files named
"foo\t-\nbar" and "foo\\011-\\012bar" being both shown
as "foo\\011-\\012bar". Fix this by including backslash
in the escaped set.
