drivers/net/wireless/{airo,ipw2100}: fix error handling bugs
airo:
* fix oops, if !CONFIG_PROC_FS (create_proc_entry always returns NULL)
* handle pci_register_driver() failure. if it fails, we really do
want to exit, rather than (as a comment indicates) return success
because-we-are-a-library.
* #if 0 have_isa_dev variable, which is assigned a value but never used
ipw2100:
* handle sysfs_create_group() failure
* handle driver_create_file() failure
