dissector: icmpv6: Fix possible null pointer dereferences
The Coverity scanner found several possible null pointer dereferences in the ICMPv6 dissector. These are all related to not checking the return value of pkt_pull(). Sometimes pkt_pull(()) is called iteratively based on a length value in the encountered packet, so this could possibly be hit in case an invalid packet is crafted accordingly. Fix all by checking the return value of pkt_pull() consistently. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

we copy the pointer from the parent (link->root = link->parent->root). Previously we recognized that Root Ports originated PCIe hierarchies, but we treated 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.
