Peter Maydell fca75f60ab target/arm: Add MO_128 entry to pred_esz_masks[] 
In commit 7390e0e9ab, we added support for SME loads and stores.
Unlike SVE loads and stores, these include handling of 128-bit
elements.  The SME load/store functions call down into the existing
sve_cont_ldst_elements() function, which uses the element size MO_*
value as an index into the pred_esz_masks[] array.  Because this code
path now has to handle MO_128, we need to add an extra element to the
array.

This bug was spotted by Coverity because it meant we were reading off
the end of the array.

Resolves: Coverity CID 1490539, 1490541, 1490543, 1490544, 1490545,
