Ferry Meng e5a4f3990a ocfs2: strict bound check before memcmp in ocfs2_xattr_find_entry() 
[ Upstream commit af77c4fc1871847b528d58b7fdafb4aa1f6a9262 ]

xattr in ocfs2 maybe 'non-indexed', which saved with additional space
requested.  It's better to check if the memory is out of bound before
memcmp, although this possibility mainly comes from crafted poisonous
images.
