[XEN PATCH] atomic: change parameter name in atomic_cmpxchg() definition

[Federico Serafini <federico.serafini@xxxxxxxxxxx>]

Change parameter name from 'ptr' to 'v' in the function definition thus
addressing violations of MISRA C:2012 Rule 8.3: "All declarations of an
object or function shall use the same names and type qualifiers".

No functional changes.
