Subject: reiserfs: use proper little-endian bitops
From: Akinobu Mita <akinobu.mita@xxxxxxxxx>
Using __test_and_{set,clear}_bit_le() with ignoring its return value can
be replaced with __{set,clear}_bit_le().
This introduces reiserfs_{set,clear}_le_bit for __{set,clear}_bit_le and
does the above change with them.
