[PATCH 1/2] tests/intel/xe_eudebug_online: Set timeout for debugger VM fd sync

[Jan Maslak <jan.maslak@intel.com>]

The vm_open_trigger() function opens a debugger VM fd via
DRM_XE_EUDEBUG_IOCTL_VM_OPEN leaving timeout_ns at zero. With a zero
timeout, fsync() on the fd may return -ETIMEDOUT immediately instead of
waiting for GPU cache invalidation to complete.

Set timeout_ns to DRM_XE_EUDEBUG_VM_SYNC_MAX_TIMEOUT_NSECS to allow
up to 10 seconds for cache invalidation to complete.
