bugfix: clock_recovery tag offsets are drifting over time
Allow enable_update_rate() so that relative rate is recalculated during
each call to work. Currently tag offsets at the output drift over time.
This fix is already applied in msk_timing_recovery_cc but is missing
from clock_recovery_mm.
See discussion about enable_update_rate:
