ocfs2: allow for more than one data extent when creating xattr

Browse source

Orabug: 18108070

ocfs2_xattr_extend_allocation() hits panic when creating xattr during
data extent alloc phase.  The problem occurs if due to local alloc
fragmentation, clusters are spread over multiple extents.  In this case
ocfs2_add_clusters_in_btree() finds no space to store more than one
extent record and therefore fails returning RESTART_META.  The situation
is anticipated for xattr update case but not xattr create case.  This
fix simply ports that code to create case.
