ocfs2: validate inline xattr header before inline refcount attach
[BUG]
A corrupt inline xattr header can make ocfs2_xattr_inline_attach_refcount()
feed an unchecked header into the refcount-attachment walk for inline
xattr values.
[CAUSE]
The inline refcount-attach path still derived the header directly from
di->i_xattr_inline_size and then passed it to code that iterates xh_count
and xattr entries.
[FIX]
Use the shared ibody header helper before attaching refcounts to inline
xattr values so corrupt header geometry is rejected with -EFSCORRUPTED
instead of being traversed.
