udev: correctly handle partition #16 and later
If a zvol has more than 15 partitions, the minor device number exhausts
the slot count reserved for partitions next to the zvol itself. As a
result, the minor number cannot be used to determine the partition
number for the higher partition, and doing so results in wrong named
symlinks being generated by udev.

Since the partition number is encoded in the block device name anyway,
let's just extract it from there instead.
