iwlwifi: pcie: dump stack on NIC error in sync commands
Many times, a NIC error is the result of a bad command sent to the device. If the command was sent synchronously, then we'll currently print a message when the command is aborted containing the command. It can be very useful to also see the stack dump though, so also print that. Reviewed-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
