[XEN PATCH 4/7] xen/arm: mem_access: address violations of MISRA C:2012 Rule 16.3

[Federico Serafini <federico.serafini@bugseng.com>]

Refactor of the code to have a break statement at the end of the
switch-clause. This addresses violations of Rule 16.3
("An unconditional `break' statement shall terminate every
switch-clause").
No functional change.
