Ejecting a PCMCIA IBM Token Ring card that has not had its dev->open()
called will reliably trigger an uninitialized spinlock oops when
spinlock debugging is enabled. The system then hangs, occasionally
softlockup oopsing.  It seems that ibmtr.c:tok_interrupt() doesn't
expect to be called before tok_open() is called, but tok_interrupt()
gets called anyway when the card is ejected.  So, set an already-extant
flag which causes tok_interrupt() to bail out early upon card ejection.
Tested by inserting and removing the PCMCIA card several times.

Applies against 2.6.21-rc5.
