[XEN PATCH 3/5] x86/irq: address violation of MISRA C Rule 5.5

[Dmytro Prokopchuk1 <dmytro_prokopchuk1@xxxxxxxx>]

Address a violation of MISRA C:2012 Rule 5.5:
"Identifiers shall be distinct from macro names".

Reports for service MC3A2.R5.5:
xen/include/xen/irq.h: non-compliant function `pirq_cleanup_check(struct pirq*, 
struct domain*)'
xen/include/xen/irq.h: non-compliant macro `pirq_cleanup_check'

The primary issue stems from the macro and function
having identical names, which is confusing and
non-compliant with common coding standards.

Change the function name by adding two underscores at the end.
