i2o: fix init/exit section usage

Fix 3 instances of bad calls to i2o_pci_free(), from init to exit code sections:
Error: ./drivers/message/i2o/pci.o .init.text refers to 000000f7 R_386_PC32 .exit.text
Error: ./drivers/message/i2o/pci.o .init.text refers to 000003bc R_386_PC32 .exit.text
Error: ./drivers/message/i2o/pci.o .init.text refers to 00000572 R_386_PC32 .exit.text
