[GIT PULL rcu/urgent] Adjust SRCU auto-expedite default delay

Hello, Ingo,

This series adds a small change to yesterday's pull request, namely
changing the default value of the srcutree.exp_holdoff kernel boot
parameter from 50 microseconds to 25 microseconds. This change completely
eliminates the performance shortfall that Mike Galbraith observed.
