Fix two issues found by syzkaller.

Patch #1 removes inappropriate usage of WARN_ON() following memory
allocation failure. Constantly triggered when syzkaller injects faults.

Patch #2 fixes a use-after-free that can be triggered by 'devlink dev
info' following a failed devlink reload.

Ido Schimmel (2):
  mlxsw: spectrum_router: Remove inappropriate usage of WARN_ON()
  mlxsw: pci: Fix use-after-free in case of failed devlink reload
