ocfs2: Use ocfs2_xattr_value_buf in ocfs2_xattr_set_entry().
ocfs2_xattr_set_entry is the function that knows what type of block it
is setting into. This is what we wanted from ocfs2_xattr_value_buf.
Plus, moving the value buf up into ocfs2_xattr_set_entry() allows us to
pass it into ocfs2_xattr_set_value_outside() and ocfs2_xattr_cleanup().
