Dan Carpenter b761fd2821 ocfs2: fix a use after free on error 
[ Upstream commit c57d117f2b2f2a19b570c36f2819ef8d8210af20 ]

The error handling in this function frees "reg" but it is still on the
"o2hb_all_regions" list so it will lead to a use after freew.  Joseph Qi
points out that we need to clear the bit in the "o2hb_region_bitmap" as
well
