[PATCH] ocfs2: Do not log twice error messages

[Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>]

'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.
