xfs, ext4, ext2: use get_random_u32_below() instead of deprecated function
JIRA: https://issues.redhat.com/browse/RHEL-36333
Now that RHEL9 has random() functions, replace deprecated prandom_xxxx() with newer get_random_xxxx() function calls. Cherry pick xfs, ext4, ext2 parts from the treewide patch.
