[XEN PATCH v2 1/2] xen/sched: address violations of MISRA C:2012 Rule 16.3

[Federico Serafini <federico.serafini@xxxxxxxxxxx>]

Add break statement to address a violation of MISRA C:2012 Rule 16.3
("An unconditional `break' statement shall terminate every
switch-clause").
Replace deprecated comment /* FALLTHRU */ with pseudo-keyword
fallthrough to meet the requirements to deviate the rule.

No functional change.

Signed-off-by: Federico Serafini <federico.serafini@xxxxxxxxxxx>

Changes in v2:
- this patch is the result of merging together two different patches with the
  same title;
- commit message has been improved to make clear that the comment is
  deprecated.
