IB/ipath: Fix crash on unload introduced by sysfs changes
Commit 23b9c1ab ("Infiniband: make ipath driver use default driver groups.") introduced a bug in the ipath driver where ipath_device_create_group() fell through into the error path, even on success, which meant that the sysfs groups it created would always get removed right away. This made ipath_device_remove_group() hit the BUG_ON() in sysfs_remove_group() when it tried to remove those groups a second time. Correct the return path so that the groups stick around until they are supposed to be cleaned up. Signed-off-by: Roland Dreier <rolandd@cisco.com>
