hw/net/fsl_etsec/etsec.c: Switch to transaction-based ptimer API

Switch the fsl_etsec code away from bottom-half based ptimers to
the new transaction-based ptimer API.  This just requires adding
begin/commit calls around the various places that modify the ptimer
state, and using the new ptimer_init() function to create the timer.
