scsi: lpfc: avoid double free of resource identifiers
Set variables initialized in lpfc_sli4_alloc_resource_identifiers() to NULL if an error occurred. Otherwise, lpfc_sli4_driver_resource_unset() attempts to free the memory again.

reated PCI/PCI-X to PCIe Bridges as being in the middle of the hierarchy, and when we tried to copy the pointer from link->parent->root, there was no parent, and we dereferenced a NULL pointer: BUG: unable to handle kernel NULL pointer dereference at 0000000000000090 IP: [<ffffffff9e424350>] pcie_aspm_init_link_state+0x170/0x820 Recognize that PCI/PCI-X to PCIe Bridges originate PCIe hierarchies just like Root Ports do, so link->root for these devices should also point to itself.
