Eric Blake 86f6748bda maint: fix comma style issues: xen 
Most of our code base uses space after comma but not before;
fix the remaining uses before adding a syntax check.

* src/libxl/libxl_driver.c: Consistently use commas.
* src/xen/xend_internal.c: Likewise.
* src/xen/xs_internal.c: Likewise.
* src/xenapi/xenapi_driver.c: Likewise.
* src/xenapi/xenapi_utils.c: Likewise.
* src/xenxs/xen_sxpr.c: Likewise.
* src/xenxs/xen_xm.c: Likewise.
