[PATCH v2] bus: fix memleak during pci device cleanup

[Kevin Laatz <kevin.laatz@intel.com>]

During PCI bus device cleanup some interrupt handle pointers and the
bus_info pointer are not being free'd, leading to memory leaks.
This patch fixes the memory leaks by ensuring they are free'd during
device cleanup on exit.

Fixes: 1cab1a40ea9b ("bus: cleanup devices on shutdown")
