Report the error in virPortAllocatorAcquire instead
of doing it in every caller.
The error contains the port range name instead of the intended
use for the port, e.g.:
Unable to find an unused port in range 'display' (65534-65535)
instead of:
Unable to find an unused port for SPICE
This also adds error reporting when the QEMU driver could not
find an unused port for VNC, VNC WebSockets or NBD migration.
