dahdi_dynamic_eth: Fix compilation on kernels < 2.6.22.

Browse Source 
Resolves the follwing build error:
  drivers/dahdi/dahdi_dynamic_eth.c: In function ‘ztdeth_exit’:
  drivers/dahdi/dahdi_dynamic_eth.c:448: error: implicit declaration of function ‘cancel_work_sync’

RHEL kernel versions 2.6.18-238 (5.6) and greater had cancel_work_sync()
backported which is what I did my original smoke test on.
