ubifs: Fix assertion in layout_in_gaps()
commit c0082e985fdf77b02fc9e0dac3b58504dcf11b7a upstream. An assertion in layout_in_gaps() verifies that the gap_lebs pointer is below the maximum bound. When computing this maximum bound the idx_lebs count is multiplied by sizeof(int), while C pointers arithmetic does take into account the size of the pointed elements implicitly already. Remove the multiplication to fix the assertion.
