IB/qib: Call kobject_put() when kobject_init_and_add() fails
[ Upstream commit a35cd6447effd5c239b564c80fa109d05ff3d114 ]
When kobject_init_and_add() returns an error in the function
qib_create_port_files(), the function kobject_put() is not called for the
corresponding kobject, which potentially leads to memory leak.
This patch fixes the issue by calling kobject_put() even if
kobject_init_and_add() fails. In addition, the ppd->diagc_kobj is released
along with other kobjects when the sysfs is unregistered.
Fixes: f931551bafe1 ("IB/qib: Add new qib driver for QLogic PCIe InfiniBand adapters")
