Move sizeof to second argument in calloc calls
Clears -Wcalloc-transposed-args warnings from gcc 14.1, such as:
mouse.c: In function ‘MousePreInit’:
mouse.c:900:32: warning: ‘calloc’ sizes specified with ‘sizeof’ in the
earlier argument and not in the later argument [-Wcalloc-transposed-args]
900 | if (!(pMse = calloc(sizeof(MouseDevRec), 1)))
| ^~~~~~~~~~~
mouse.c:900:32: note: earlier argument should specify number of elements,
later size of each element
