clk: si5341: free unused memory on probe failure

Pointers from synth_clock_names[] should be freed at the end of probe
either on probe success or failure path.

Fixes: b7bbf6e ("clk: si5341: Allow different output VDD_SEL values")
Fixes: 9b13ff4 ("clk: si5341: Add sysfs properties to allow checking/resetting device faults")
