[libvirt] [PATCH] Remove redundant virFileDeletePID() call

[Chris Lalancette <clalance@xxxxxxxxxx>]

qemudShutdownVMDaemon() calls qemudRemoveDomainStatus(), which
then calls virFileDeletePID().  qemudShutdownVMDaemon() then
unnecessarily calls virFileDeletePID() again.  Remove this second
usage of it, and also slightly refactor qemudRemoveDomainStatus()
to VIR_WARN appropriate error messages.
