rcu: Avoid double multiply by HZ
The rcu_check_gp_start_stall() function multiplies the return value
from rcu_jiffies_till_stall_check() by HZ, but the units are already
in jiffies. This commit therefore avoids the need for introduction of
a jiffies-squared unit by removing the extraneous multiplication.
