SLIC_LF_OPPENDING confict between wctdm_proslic_recheck_sanity() and set_lasttxhook_interruptible()

Problem:

'wctdm_proslic_recheck_sanity()' is executed (4 times??) every ~256ms which monitors and clears the SLIC_LF_OPPENDING on fxs->lasttxhook when the LF state has been reached.
  
'set_lasttxhook_interruptible()' times out after 100ms waiting from the previous write to the SLIC_LF register, by waiting for SLIC_LF_OPPENDING to be cleared, thus the write will fail.

Solution:
adds wctdm_proslic_check_oppending which does the monitoring and clearing of SLIC_LF_OPPENDING, which is execute every 1ms. It also if the correct state is not reached within 100ms, resends the lasttxhook state.
