ocfs2: do not log twice error messages
'o2hb_map_slot_data' and 'o2hb_populate_slot_data' are called from only
one place, in 'o2hb_region_dev_write'. Return value is checked and
'mlog_errno' is called to log a message if it is not 0.
So there is no need to call 'mlog_errno' directly within these functions.
This would result on logging the message twice.
