RDMA/irdma: Add a missing kfree of struct irdma_pci_f for GEN2

During a refactor of the irdma GEN2 code, the kfree of the irdma_pci_f struct
in icrdma_remove(), which was originally introduced upstream as part of
commit 80f2ab4 ("irdma: free iwdev->rf after removing MSI-X")
was accidentally removed.
