[XEN PATCH v2 3/4] xen/vpci: address violations of MISRA C Rule 16.3

[Federico Serafini <federico.serafini@xxxxxxxxxxx>]

Address violations of MISRA C:2012 Rule 16.3:
"An unconditional `break' statement shall terminate every
switch-clause".

No functional change.

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

Changes from v2:
- simply break without returning X86EMUL_UNHANDLEABLE.

As pointed out by Jan, these functions only return X86EMUL_OKAY but:
