iwmc3200wifi: Return proper error for iwm_if_alloc
In the case of alloc_netdev_mq failure and kmalloc failure,
current implementation returns ERR_PTR(0).
As a result, the caller of iwm_if_alloc does not catch the error by IS_ERR
macro. Fix it by setting proper error code for ret variable in the failure
cases.
