Fix number of available printers in CUPS support
If available printers in CUPS support.
If the number of available printers changes, we want
to update the count. Additionally, if that number has
gone to zero, we want to ensure that the number of
available printers in the static object is reset to
zero.
This fixes a crash that occurs if:
* You print
* You kill cupsd (or it crashes because you're porting it and your port is
* unstable)
* You try to print again before restarting it.
