RedHat: Fail openafs-client 'stop' on rmmod error

Currently, the openafs-client RPM init script ignores any error
reported by rmmod. If 'umount /afs' succeeds but rmmod does not, the
client may panic the machine if the client is started again (from e.g.
running the 'restart' init script method), since afsd will try to
initialize AFS with a libafs that has been shut down.

So, do not ignore errors from 'rmmod', and instead fail the 'stop'
method from the init script if we get an error.
