Minor cleanups to acpi_pci_set_power_state(): use the ACPI and PCI
state symbols to make clear that a mapping is being done between PCI
and ACPI states, instead of using magic numbers. For paranoia's sake,
report any errors. Save five bytes (x86_64) too.

This patch (as1033) adds a quirks entry and an unusual_devs entry for

string descriptor, which it doesn't terminate with a 0-length packet.
Oddly enough, the reporter's logs show that when the device was
plugged in at boot time, it changes its behavior completely -- it uses
a different product ID, product string descriptor, and bDeviceClass.

This patch (as1032) removes the Clear-Halt calls in
usb_stor_Bulk_max_lun(). Evidently some devices (such as the Oracom
MP3 player) really don't like to receive these requests when their
bulk endpoints aren't halted.
The only reason for adding them originally was to get an ancient
ZIP-100 drive to work. But since this device has only a single LUN,
we don't need to send it a Get-Max-LUN request at all. Adding an
unusual_devs entry for the ZIP-100 with the SINGLE_LUN flag set will
cause this step to be skipped.

Fix wrong counter check for proc_dir_entry in pci_proc_detach_device().
The pci_proc_detach_device() returns with -EBUSY before calling
remove_proc_entry() if the reference counter of proc_dir_entry is not
0. But this check is wrong and pci_proc_detach_device() always fails
because the reference counter of proc_dir_entry is initialized with 1
at creating time and decremented in remove_proc_entry(). This bug
cause strange behaviour as followings:
- Accessing /proc/bus/pci/XXXX/YY file after hot-removing pci adapter
card causes kernel panic.
- Repeating hot-add/hot-remove of pci adapter card increases files
with the same name under /proc/bus/pci/XXXX/ directory. For example:
# pwd
/proc/bus/pci/0002:09
# ls
01.0
# for i in `seq 5`
> do
> echo 0 > /sys/bus/pci/slots/0009_0032/power
> echo 1 > /sys/bus/pci/slots/0009_0032/power
> done
# ls
01.0 01.0 01.0 01.0 01.0 01.0
The pci_proc_detach_device() should check if the reference counter is
not larger than 1 instead.
