Randy Dunlap d27b1f84c0 net: sched: prevent invalid Scell_log shift count
[ Upstream commit bd1248f1dd ]

Check Scell_log shift size in red_check_params() and modify all callers
of red_check_params() to pass Scell_log.

This prevents a shift out-of-bounds as detected by UBSAN:
  UBSAN: shift-out-of-bounds in ./include/net/red.h:252:22
  shift exponent 72 is too large for 32-bit type 'int'

Fixes: 8afa10cbe2 ("net_sched: red: Avoid illegal values")
