cxl: Fix kobject memleak

[ Upstream commit 85c5cbeba8f4fb28e6b9bfb3e467718385f78f76 ]

Currently the error return path from kobject_init_and_add() is not
followed by a call to kobject_put() - which means we are leaking
the kobject.

Fix it by adding a call to kobject_put() in the error path of
kobject_init_and_add().
