In virObjectLockableNew, when virMutexInit fails,
virReportSystemError should use errno to get the right

I'm not sure errno is set when using our virMutexInit().  Most of the
code uses virReportError instead, I suggest using that.  This should
be changed everywhere in the code.  Rough idea of the places could be
gotten by the following command:

git grep -nA5 virMutexInit | grep SystemError

but as I said, only rough idea :)
