[PATCH i-g-t 1/2] tests/intel/xe_mmap: Fix open/close calls

[Kolanupaka Naveena]

Code used open()/close() APIs from standard C library to open and close
the driver respectively while it should be drm_open_driver() and
drm_close_driver(). As we already have fd opened, use more suitable
function which is drm_reopen_driver().

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