  systemd-udev cause high cpu load after upgrade to bionic

Bug description:
  After upgraded from xenial to bionic (kernel 4.15.0-20) systemd-udevd
  runs with high cpu load in 2 instances (50%, 15%) on Dell Precision
  M6500 when wlan switch will be enabled.

  With xenial this problem did't happen and Dell bluetooth & wifi (b43)
  are working.

  After some research I found that /var/log/syslog gets filled with a
  lot of messages (see log sample below).

  If I modify /lib/udev/rules.d/97-hid2hci.rules (disable rule for
  413c:8154, 413c:8158, 413c:8162), restart udev, turn wifi off/on by
  hardware switch, the messages go away but the bluetooth adapter will
  be not enabled anymore. It seems that udev is running in a loop.

  My modification for the rule just was (just as proof):

  --- before ---
  ATTR{bInterfaceClass}=="03", ATTR{bInterfaceSubClass}=="01", 
ATTR{bInterfaceProtocol}=="02", \
ATTRS{bDeviceClass}=="00", ATTRS{idVendor}=="413c", 
ATTRS{bmAttributes}=="e0", \
RUN+="hid2hci --method=dell --devpath=%p", ENV{HID2HCI_SWITCH}="1"
  --- end before ---

  --- after ---
  ATTR{bInterfaceClass}=="03", ATTR{bInterfaceSubClass}=="01", 
ATTR{bInterfaceProtocol}=="02", \
ATTRS{bDeviceClass}=="00", ATTRS{idVendor}=="413c", 
ATTRS{bmAttributes}=="e0", \
RUN+="/bin/sh", ENV{HID2HCI_SWITCH}="1"
  --- end after ---

  If you need some experiment or testing I can do (compiling software is
  not a problem, I'm a developer).
