[PATCH i-g-t 2/2] tests/intel/xe_mmap: Fix open/close calls

[Kolanupaka Naveena]

Instead of using the standard drm_open and close APIs for driver
open and close operations, use the appropriate drm_reopen and
drm_close APIs to ensure the driver is opened and closed correctly.

Also drop the srand() call as this is already taken care by igt-core.
