xen/ioreq: address violations of MISRA C:2012 Rule 7.3

The xen sources contain violations of MISRA C:2012 Rule 7.3 whose headline
states:
"The lowercase character 'l' shall not be used in a literal suffix".

Use the "L" suffix instead of the "l" suffix, to avoid potential ambiguity.
If the "u" suffix is used near "L", use the "U" suffix instead, for consistency.

The changes in this patch are mechanical.
