drivers/misc: Move misplaced pci_dev_put's

Move pci_dev_put outside the loops in which it occurs.  Within the loop,
pci_dev_put is done implicitly by pci_get_device.

The problem was detected using the following semantic patch, and corrected
by hand.

@@
expression dev;
expression E;

- pci_dev_put(dev)
   ... when != dev = E
- pci_get_device(...,dev)
