Flooding udev change events for /dev/sdb cause high CPU load.

[navid-zamani]

When the system starts, udisks2 causes an infinite repetition of these events:

KERNEL[1832.422273] change   /devices/pci0000:00/0000:00:01.2/0000:15:00.1/ata2/host1/target1:0:0/1:0:0:0/block/sdb/sdb1 (block)
KERNEL[1832.628578] change   /devices/pci0000:00/0000:00:01.2/0000:15:00.1/ata2/host1/target1:0:0/1:0:0:0/block/sdb/sdb2 (block)
UDEV  [1832.643786] change   /devices/pci0000:00/0000:00:01.2/0000:15:00.1/ata2/host1/target1:0:0/1:0:0:0/block/sdb/sdb1 (block)
UDEV  [1832.732081] change   /devices/pci0000:00/0000:00:01.2/0000:15:00.1/ata2/host1/target1:0:0/1:0:0:0/block/sdb/sdb2 (block)

This causes a high CPU load.

Only stopping and masking the udisks2 daemon/service prevents this from coming back after the next trigger.
