clk: fix a panic error caused by accessing NULL pointer
In some cases the clock parent would be set NULL when doing re-parent,
it will cause a NULL pointer accessing if clk_set trace event is
enabled.
This patch sets the parent as "none" if the input parameter is NULL.
Fixes: dfc202ead312 (clk: Add tracepoints for hardware operations)
