uhd: reset sample clock when time goes non-monotonic

With UHD b4fc0d61bb6cbd1a5614745bab9aeb0abc22cb6f

Sample clock will reset to zero after an overrun. Earlier
versions may hang the FPGA, which is non-recoverable,
requiring a manual image reload or reboot.

If reset to zero, attempt to kick the sample clock to the
last properly received timestamp value. At this point,
there will be a timing continuity jump, which will drop
connections, but transmit and receive chains should be
aligned allowing for re-establishment.
