Somehow, it is possible to get a pcicintr() when in the resume process.

Browse Source 
This will trigger inserted()) to be called twice which confuses pccardd.
Add code to not process pcicitr())'s when in the middle of a resume
process. The real insertion of cards and the emulated one in the suspend/resume
code really do not mix up.
