Joshua DeWeese 4d39d6e2f3 sys/isrpipe: fix init of mutex ...

The mutex used to sync the reader and writer of the pipe is initialized
as unlocked. This results in a bit of wasted CPU cycles the first time a
read blocks. This patch inits the mutex in a locked state so that the
first blocking read blocks immediately.
