[Luca Fancellu <luca.fancellu@xxxxxxx>]

In this serie there are some fixes for the rule 20.7, mainly violation found by
cppcheck, most of them are false positive but some of them can be fixed.

The analysed build is arm64, to reproduce the reports here the command:

./xen/scripts/xen-analysis.py --cppcheck-misra --run-cppcheck -- 
CROSS_COMPILE="aarch64-linux-gnu-" XEN_TARGET_ARCH="arm64" 
O=/path/to/artifacts_folder
