treewide: use get_random_u32() when possible

2022-10-11T23:42:58Z

The prandom_u32() function has been a deprecated inline wrapper around get_random_u32() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. The same also applies to get_random_int(), which is just a wrapper around get_random_u32(). This was done as a basic find and replace.

Pull SCSI updates from James Bottomley: "Updates to the usual drivers (qla2xxx, lpfc, ufs, hisi_sas, mpi3mr, mpt3sas, target).
