[PATCH v4 15/24] ocfs2: use little-endian bitops

[Akinobu Mita]

As a preparation for removing ext2 non-atomic bit operations from
asm/bitops.h.  This converts ext2 non-atomic bit operations to
little-endian bit operations.

Change from v3:
 - change to the post-fix notation e.g. s/test_le_bit/test_bit_le/
